TeSys GV2 Motor Circuit Breakers, GV2ME Manual Motor Starter — Cross-Reference Guide for GV2ME Substitutes

When a controls engineer or panel builder needs to substitute or cross-reference a Schneider Electric TeSys GV2ME manual motor starter, the decision is rarely as simple as pulling the first matching current range from a competitor catalog. The GV2ME is a thermal-magnetic motor circuit breaker that delivers both overload protection and short-circuit protection in a single device, without requiring an external thermal overload relay for most applications — and not every alternative series works the same way. Whether the driver is a supply chain gap, an ecosystem consolidation to Allen-Bradley, Siemens, Eaton, or ABB, or a project-specific approval requirement, this guide maps the practical substitution paths so engineers can specify with confidence.

Who Should Use This Guide — and What to Confirm Before You Specify

This guide is written for controls engineers, panel builders, and OEM designers who need a validated cross-reference path, not a guess. It is the right resource if your situation matches any of these conditions:

  • You need a GV2ME replacement because your usual distributor is out of stock or lead times are unacceptable for your build schedule.
  • You are standardizing a machine or plant to a different controls ecosystem (Allen-Bradley, Siemens, Eaton, or ABB) and need to understand what motor protection product replaces GV2ME in that ecosystem.
  • Your project requires specific UL, CSA, or IEC approval categories that need to be verified against the available substitute options.
  • You are evaluating whether GV2RT or GV2L/GV2M within the TeSys GV2 family is a more appropriate choice for a specific motor application, such as a motor with high peak starting current.
  • You are a maintenance planner handling a single-unit field replacement and need to understand the minimum validation steps before swapping devices.

If your priority is minimizing engineering change, stay within the TeSys GV2 family. If ecosystem alignment or availability forces a cross-brand move, this guide identifies the substitution effort involved. Cross-brand substitution is feasible but requires more engineering validation than staying within Schneider's TeSys GV2 product line.

What the TeSys GV2ME Actually Does in a Motor Starter Circuit

The TeSys GV2ME is classified as an IEC thermal-magnetic motor circuit breaker and manual motor starter. Its core function is to provide both thermal overload protection and magnetic short-circuit protection for a motor in a single compact device, eliminating the need for a separate thermal overload relay in most standard applications. Control is via push buttons — on and off — which makes the GV2ME the standard selection for normal motor applications where an operator interface on the enclosure door is required.

It is important to distinguish the GV2ME from other devices in the same TeSys GV2 family. The GV2L is a magnetic-only motor starter — it protects against short circuits but does not provide thermal overload protection, meaning a separate overload relay is required in the circuit. The GV2M is a manual starter that adds thermal overload. The GV2RT uses a rocker lever instead of push buttons and is designed specifically for motors with high peak starting current — applications where a standard thermal-magnetic trip would be too sensitive to the starting transient. None of these variants are interchangeable without understanding what each one does and does not protect.

Short-circuit ratings, adjustable thermal current ranges, and approval markings are specific to individual catalog numbers within each series. The series name alone is not sufficient for substitution decisions — the exact catalog number and its datasheet must be consulted for every protection and coordination parameter.

Where GV2ME Sits in a Typical Motor Control Architecture

The GV2ME sits directly in the branch circuit ahead of the motor contactor, acting as both the manual isolation point and the protective device for the motor branch. Understanding its position in the signal and power chain helps clarify what any substitute must replicate.

  • Upstream: Panel main breaker or MCC bus feeding the motor branch circuit.
  • GV2ME or substitute: Provides manual on/off control, thermal overload protection, and magnetic short-circuit protection — the combined function of a motor protection circuit breaker.
  • Downstream — Motor contactor: The contactor handles automatic motor switching; the GV2ME provides protection and isolation upstream of it.
  • Downstream — Motor terminals: Motor is connected through the contactor; GV2ME trip disconnects the entire branch.
  • Auxiliary contacts and accessories: Trip indication signals, remote auxiliary contacts, and door-interlock handles are typically added as accessories to the GV2ME or its substitute.

Typical Applications and Industries Where GV2ME Is Specified

The GV2ME and its equivalents appear most frequently in small to medium IEC motor applications across manufacturing, packaging, food and beverage, automotive, HVAC, and pumping. Panel builders use it in combination motor starter assemblies inside control enclosures and MCC buckets. OEMs specify it for machine-level motor protection where a single device covers isolation, overload, and short-circuit functions without adding a separate overload relay to the BOM.

Maintenance planners encounter it when a motor protection device fails and must be replaced quickly from local stock, sometimes requiring a cross-brand substitute when the original is not available from the nearest distributor. Purchasing teams encounter it when standardizing spare parts across a multi-vendor facility and need a single alternate part number that can satisfy multiple installation points.

Application Typical Deployment
Combination motor starter in control panel GV2ME ahead of contactor, providing both isolation and full motor protection without separate overload relay
MCC bucket motor protection GV2ME or cross-brand equivalent as the motor protective circuit breaker in an IEC motor control center bucket
Packaging machine motor control GV2ME for standard-duty motors; GV2RT considered where high inrush from rapid cycling causes nuisance trips
HVAC fan and pump motor protection GV2ME in standalone or grouped motor starter panels, often with door-interlock handle accessory
Food and beverage conveyor drives GV2ME or IEC equivalent (140M, 3RV2) selected based on plant's preferred controls ecosystem
Field replacement in mixed-vendor facility GV2ME preferred if available; cross-brand substitute after confirming mechanical fit, approvals, and coordination

How Each Alternative Handles Thermal and Magnetic Protection

One of the most important functional distinctions when selecting a GV2ME substitute is whether the replacement device provides thermal overload protection internally or requires an external overload relay. Getting this wrong changes both the BOM and the panel wiring.

Alternative-by-Alternative Decision Breakdown

TeSys GV2RT — Schneider In-Family Option for High Inrush Motors

The TeSys GV2RT Motor Circuit Breakers share the same TeSys GV2 platform and thermal-magnetic protection concept as the GV2ME. The critical difference is the control interface and the motor application profile: GV2RT uses a rocker lever rather than push buttons, and it is specifically designed for motors with high peak starting current. If a GV2ME is experiencing nuisance trips during motor starting due to high inrush, and the motor's starting characteristics genuinely demand it, GV2RT is the correct within-family substitute — not an arbitrary upgrade. However, the change in control interface from push buttons to rocker lever may require a panel layout review and operator communication update. Within the Schneider ecosystem, accessories, DIN-rail mounting, and coordination documentation remain largely compatible.

TeSys GV2L and GV2M — When External Thermal Protection Is Preferred

The TeSys GV2L Magnetic Motor Starters and GV2M Manual Starters serve architectures where the designer prefers to separate short-circuit protection from thermal overload protection. The GV2L is magnetic-only — it does not provide thermal overload protection, making a separate overload relay mandatory. The GV2M includes thermal overload. Neither GV2L nor GV2M are UL489-listed as general-purpose circuit breakers, which is a meaningful distinction for installations where listing categories are inspected. Switching from GV2ME to GV2L in an existing panel adds a device and additional wiring, so this path is typically justified only when the architecture actively benefits from separate protection elements — not as a pure availability substitute.

Allen-Bradley Bulletin 140M — For Allen-Bradley Ecosystem Panels

The 140M Motor Protection Circuit Breakers provide IEC thermal-magnetic motor protection and manual isolation comparable in function to the GV2ME, and they integrate directly with Allen-Bradley contactors and MCC designs. For OEMs or plants that are already standardized on Allen-Bradley drives and PLCs, specifying 140M in place of GV2ME significantly simplifies the spare-parts library, coordination documentation, and engineering support chain. The 140M catalog structure, accessory numbering, and approval documentation differ from Schneider's, so a direct cross-reference requires reviewing each catalog number's specific current range, short-circuit rating, and approval markings — not just the series designation. Mechanical dimensions and door-interlock accessories are not interchangeable with TeSys components.

Siemens SIRIUS 3RV2 — For Siemens-Centric Control Cabinets

The SIRIUS 3RV2 Circuit Breakers for Motor Protection are the natural GV2ME equivalent in a Siemens SIRIUS control gear environment. They offer adjustable thermal and magnetic protection coordinated with Siemens contactors and engineered to fit within SIRIUS assembly systems. Engineers switching from GV2ME to 3RV2 in a retrofitted panel should expect mechanical dimension differences and a need to re-select door-interlock handle kits and any front-mounting accessories. Coordination data must be re-verified using Siemens documentation, as tables from Schneider do not apply to 3RV2 devices.

Eaton PKZM0 and PKE — Thermal-Magnetic and Electronic Options

Eaton's Motor Protective Circuit Breakers PKZM0 / PKE cover the same functional territory as GV2ME, with PKZM0 providing conventional bimetallic thermal-magnetic protection and PKE offering electronic trip with adjustable characteristics and basic diagnostic capability. For applications in Eaton-based MCCs or panels, the PKZM0 or PKE is the preferred path — accessory compatibility, coordination tables, and engineering support all align with the Eaton ecosystem. The PKE electronic trip variant is worth considering where trip adjustability, communication, or fault diagnostics add value beyond what a conventional bimetallic device offers.

ABB MS116 and MS132 — For ABB Contactor and Motor Starter Systems

The ABB Manual Motor Starters MS series — specifically MS116 and MS132 — deliver thermal-magnetic motor protection and manual control with direct mounting compatibility to ABB contactors and motor starter assemblies. They are the functionally appropriate GV2ME substitute for OEMs that have adopted ABB as their primary control brand. Adjustment range, accessory catalog, and coordination data are ABB-specific, and all three must be evaluated from ABB documentation before finalizing a substitution. The MS116 and MS132 are different frame sizes covering different current ranges; selecting the correct frame for the motor's FLA is a mandatory step before specifying either.

Switching Brands: What the Migration Actually Involves

The effort to migrate from GV2ME to a cross-brand alternative is consistently underestimated in the field. The table below maps the migration dimensions for each substitution path. Ratings of low, medium, and high reflect relative engineering effort, not absolute difficulty.

From GV2ME To Mechanical Changes Wiring Changes Coordination/Approval Recheck Level Documentation Impact
TeSys GV2RT Low — same platform; handle/interface change only Low — same wiring architecture Low — same family; verify current range and inrush suitability Low — update device tag and operator labels
TeSys GV2L / GV2M Medium — GV2L requires adding overload relay; GV2M is similar footprint Medium — GV2L adds overload relay wiring; GV2M similar Medium — coordination must account for separate overload relay where applicable Medium — BOM, schematic and approval section updates
Allen-Bradley 140M High — different dimensions, mounting, door-interlock hardware Medium to High — terminal layout and auxiliary contact positions differ High — full re-verification against AB coordination tables and UL/CSA approvals High — schematics, BOM, labels, panel schedule, maintenance manual
Siemens SIRIUS 3RV2 High — different frame dimensions and accessory system Medium to High — terminal layout differences; re-verify auxiliary contacts High — Siemens coordination data required; approvals to be confirmed per catalog number High — full documentation update required
Eaton PKZM0 / PKE High — different frame and accessory mounting system Medium to High — Eaton-specific terminal and auxiliary layout High — re-verify short-circuit rating, coordination and approvals using Eaton data High — full documentation update required
ABB MS116 / MS132 High — different frame; verify frame size (MS116 vs MS132) for current range Medium to High — ABB terminal layout and auxiliary contacts differ High — ABB coordination tables required; approval markings to be confirmed per catalog number High — full documentation update required

Best Alternative by Application Scenario

The following scenario matrix translates the alternatives framework into direct application guidance. Each recommendation reflects the lowest-risk substitution path for the described situation.

Scenario Recommended Alternative Key Reason
Schneider-based OEM panel with normal-duty IEC motors; GV2ME backordered TeSys GV2ME (matching current range) or TeSys GV2RT only if starting characteristics require it Minimal engineering change; same ecosystem and accessories
Schneider-based application with motors showing very high starting currents TeSys GV2RT matched to motor FLA and starting profile GV2RT is designed for special motors with high peak starting current; rocker-lever interface is acceptable
Plant standardizing on Allen-Bradley components and drives Allen-Bradley Bulletin 140M coordinated with AB contactors Ecosystem alignment reduces spare-part complexity and documentation burden
Panel builder shifting to Siemens SIRIUS control gear Siemens SIRIUS 3RV2 series Native fit with Siemens starters, accessories, and coordination documentation
Water treatment facility or process plant standardizing on Eaton Eaton PKZM0 or PKE series matched to motor current Consistency with Eaton MCC components; PKE adds electronic trip where diagnostics add value
OEM adopting ABB as primary control brand ABB MS116 or MS132 depending on motor current range Direct integration with ABB contactors and motor starter assemblies
Mixed-vendor plant needing fast single-unit replacement for one GV2ME Evaluate staying with GV2ME or GV2RT first; cross-brand only after confirming mechanical fit, approvals, and coordination Minimizes risk and engineering changes for isolated single-unit replacements

Expert Verdict: Which Substitute Is Right for Your Situation

For the majority of projects, the lowest-risk substitution path for the TeSys GV2ME manual motor starter is another correctly specified device within the Schneider TeSys GV2 family. The GV2ME itself — matched precisely to the motor's full-load current range — remains the cleanest answer for any Schneider-based panel when availability allows. Where the motor application involves high peak starting current that a standard GV2ME does not handle reliably, the TeSys GV2RT Motor Circuit Breakers are the appropriate in-family move: same thermal-magnetic protection platform, same ecosystem, different control interface. The GV2L and GV2M paths make sense only where the panel architecture deliberately separates short-circuit protection from thermal overload protection — not as a convenience substitution. Every in-family substitution still requires verifying the exact catalog number's current range, short-circuit rating, and approval markings; the series name alone is not sufficient.

Cross-brand substitution with the Allen-Bradley 140M Motor Protection Circuit Breakers, Siemens SIRIUS 3RV2 Circuit Breakers for Motor Protection, Eaton Motor Protective Circuit Breakers PKZM0 / PKE, or ABB Manual Motor Starters MS116 / MS132 is technically credible in the right ecosystem context — but it is not a simple swap. Mechanical dimensions, accessory systems, coordination tables, and approval documentation all change when you cross brands. Engineers who have done this in the field report that the extra work in coordination studies, panel layout adjustments, and documentation updates is real and should be scoped before the substitution decision is made. Choosing a cross-brand substitute purely because it appears in the same current range category without verifying short-circuit ratings, approval categories, and mechanical fit is the single most common mistake made during these substitutions.

From a procurement standpoint, working with a distributor who understands IEC motor protection at the catalog-number level — not just the series level — saves significant time during the evaluation process.

What Engineers Who Have Made This Switch Report

Controls engineers and panel builders who have worked through GV2ME cross-reference decisions in PLC and automation communities share a consistent theme: the functional concept of manual motor protection is well understood across all major IEC brands, but the variant-naming confusion within each family and the coordination data differences between brands are where projects get delayed. Within the Schneider TeSys GV2 family, the most frequently reported confusion is between GV2ME, GV2L, GV2M, and GV2RT — specifically around whether a given device provides built-in thermal overload protection and which motor starting profile it is designed for. Engineers who have specified GV2L expecting full GV2ME protection, or GV2ME in a high-inrush application that needed GV2RT, describe these as expensive corrections after the panel was already assembled.

For cross-brand substitutions, the Allen-Bradley 140M and Siemens SIRIUS 3RV2 draw the most community discussion. The 140M earns consistent praise for its integration into Allen-Bradley MCC and starter assemblies and for the depth of its coordination documentation, but engineers note that it is only the right call when the rest of the panel is already in the AB ecosystem — specifying it as a standalone substitute in a Schneider panel creates more work than it solves. The 3RV2 draws similar comments around its compact mechanical design and SIRIUS system fit, with complaints focused on the mechanical dimension differences that require layout changes when retrofitting an existing enclosure designed around TeSys hardware. The Eaton PKZM0 and ABB MS series are well-regarded in their respective ecosystems, with users noting that the main learning curve is the new catalog structure and coordination table format rather than the protection function itself.

The recurring practical advice from the community: never finalize a cross-brand substitution based on a current range match alone. Verify the short-circuit rating and coordination data for the exact catalog number, confirm the approval markings against project requirements, and check mechanical fit against the enclosure drawings before ordering. These are not cautionary generalizations — they are the specific steps engineers who have had to rework panels after incorrect substitutions wish they had taken at the BOM stage. LeadTime.ca's sourcing team fields these exact cross-reference questions regularly and can help narrow the shortlist before the engineering review begins.

Installation and Wiring Considerations for GV2ME and Substitutes

  • GV2ME and in-family TeSys GV2 devices mount on standard DIN rail; cross-brand alternatives also DIN-rail mount but with different spacing and cutout requirements — verify enclosure drawings before finalizing the substitute selection.
  • Terminal positions, wire entry directions, and maximum conductor sizes differ between GV2ME and cross-brand alternatives; confirm against the specific substitute's dimensional drawing before wiring the enclosure.
  • Auxiliary contact blocks, shunt trip accessories, and door-interlock handle kits are not interchangeable across brands — re-select all accessories for the substitute device, not just the main device.
  • For any motor protection device replacement, apply lockout/tagout procedures and ensure work is performed by qualified personnel; functional testing of motor starting, overload trip, and short-circuit trip performance must be completed after substitution.
  • Always reference the substitute manufacturer's installation and wiring documentation — do not rely on GV2ME installation procedures when commissioning a cross-brand replacement.

Wrong-Part Prevention Checklist Before You Order

Before finalizing any GV2ME substitute — whether within the TeSys GV2 family or cross-brand — work through each item on this checklist at the catalog-number level, not the series level:

  1. Confirm motor FLA and ensure chosen breaker's thermal range covers it without exceeding limits.
  2. Verify short-circuit rating and coordination data for the specific catalog number, not just the series.
  3. Check mechanical compatibility: DIN-rail spacing, door-interlocking, and front-mounting requirements.
  4. Confirm voltage ratings, insulation category and breaking capacity meet the installation.
  5. Match control interface (push buttons vs rocker lever) to operator expectations and panel layout.
  6. Ensure approvals (UL category, CSA, IEC) align with the project jurisdiction and standards.
  7. Validate accessories (aux contacts, shunt trips, enclosures) are available and compatible.

If you need sourcing help confirming any of these parameters for available stock, contact the LeadTime.ca team — we can cross-reference catalog numbers and confirm current availability worldwide.

Common Mistakes When Choosing GV2ME Alternatives

Selecting a Substitute on Current Rating Alone

Matching motor FLA to the breaker's thermal adjustment range is necessary but not sufficient. Short-circuit breaking capacity, coordination type with the upstream breaker and downstream contactor, and approval category are all variant-specific. A device that covers the right current range but carries an inadequate short-circuit rating for the installation is a liability, not a solution. Always pull the datasheet for the exact catalog number and verify all protection parameters before finalizing the BOM.

Assuming Mechanical Drop-In Compatibility

IEC motor protective circuit breakers are not a standardized physical form factor. Frame dimensions, terminal positions, DIN-rail footprint, door-interlock handle systems, and front-mount accessory kits all vary between Schneider, Allen-Bradley, Siemens, Eaton, and ABB. Verifying mechanical fit against enclosure drawings and confirming accessory availability before ordering is a mandatory step, not an optional check.

Ignoring Approval and Listing Category Differences

The GV2ME and comparable products from other brands are motor protective devices — not general-purpose UL489 circuit breakers. Approval categories, listing types, and IEC/UL/CSA marking combinations differ across variants and brands. Inspectors and project standards may require specific listing types, and assuming equivalence between an IEC-only and a UL-listed device can create compliance issues late in the project cycle when corrections are most costly.

Overlooking Operator Interface and Auxiliary Function Changes

Substituting a push-button-controlled GV2ME with a rocker-lever GV2RT or a rotary-handle cross-brand device is not purely a mechanical difference — it affects operator expectations, panel labeling, and sometimes safety procedures. Similarly, auxiliary contact arrangements, trip indication signals, and remote reset functions may differ between the substitute and the original device. These differences must be reviewed before the substitution is approved for a working installation.

Switching Brand Without Reevaluating Coordination Studies

Coordination between the motor protective circuit breaker, the upstream branch breaker, and the downstream contactor is specific to the exact devices involved — it is not transferable from one brand to another within the same current range. When a cross-brand substitute is selected, the coordination study must be re-run using the substitute manufacturer's coordination tables. Assuming the original Schneider coordination data remains valid when the protection device has changed to 140M, 3RV2, PKZM0, or MS series is a risk that has caused real field failures.

Frequently Asked Questions

Is the GV2ME a circuit breaker or a manual motor starter — and does the classification matter for substitution?

The TeSys GV2ME manual motor starter is classified as an IEC thermal-magnetic motor circuit breaker and manual motor starter — not as a general-purpose UL489 circuit breaker. This classification matters because the approval category, coordination method, and application scope differ from a standard branch circuit breaker. When selecting a substitute, the replacement device must carry the appropriate motor protection listing for the installation's jurisdiction and standards — not simply any device that fits the current range.

Can GV2ME be directly replaced by GV2RT without other changes?

The TeSys GV2RT Motor Circuit Breakers operate on the same thermal-magnetic protection platform as the GV2ME and share the same TeSys GV2 ecosystem, but the control interface changes from push buttons to a rocker lever. In most cases this is an in-panel change that requires updating operator labeling and confirming the panel cutout accommodates the GV2RT's interface. The substitution is appropriate when the motor's starting characteristics — specifically high peak starting current — justify using GV2RT. It is not automatically a like-for-like drop-in simply because GV2ME is unavailable; the motor application must be assessed first.

When should GV2L or GV2M be used instead of GV2ME?

The TeSys GV2L Magnetic Motor Starters are appropriate only when thermal overload protection is deliberately provided by a separate overload relay in the circuit — the GV2L itself provides no thermal protection. The TeSys GV2M Manual Starters add thermal overload protection and are functionally closer to GV2ME. Neither path should be chosen as a simple availability substitute for GV2ME without understanding the protection architecture change involved, particularly for the GV2L, which adds a device to the BOM and changes the wiring.

What is the Allen-Bradley equivalent to GV2ME?

The Allen-Bradley Bulletin 140M Motor Protection Circuit Breakers are the functional equivalent of GV2ME within the Rockwell Automation ecosystem. They provide IEC thermal-magnetic motor protection and manual isolation, and they integrate with Allen-Bradley contactors and MCC assemblies. Selecting the correct 140M catalog number requires matching the motor's FLA to the device's adjustable thermal range and verifying the short-circuit rating, approval markings, and mechanical fit — the same verification steps required for any substitute selection.

What Siemens SIRIUS part corresponds to GV2ME?

The Siemens SIRIUS 3RV2 Circuit Breakers for Motor Protection are the Siemens ecosystem equivalent. They provide comparable thermal-magnetic motor protection and manual control for IEC motors and integrate with SIRIUS contactors and accessories. As with all cross-brand substitutions, current range, short-circuit rating, approvals, and mechanical dimensions must be verified against the specific 3RV2 catalog number — they are not identical to GV2ME parameters.

Do alternatives share the same short-circuit rating as GV2ME?

No. Short-circuit ratings are specific to individual catalog numbers within each product series, and they are not standardized across brands. A 140M, 3RV2, PKZM0, or MS series device in the same current range as a GV2ME may have a different short-circuit breaking capacity, and the coordination type with upstream and downstream devices will differ. Engineers must consult each manufacturer's catalog or datasheet for exact short-circuit ratings and must run or review coordination studies using the substitute manufacturer's documentation — never assume the Schneider coordination data applies to a cross-brand replacement.

Can I mix motor protective circuit breakers and contactors from different brands?

In some cases yes, but it requires careful validation. Manufacturers publish coordination data for their own devices used with their own contactors — Type 1 and Type 2 coordination ratings, for example, are typically provided for same-brand combinations. Using a GV2ME with a non-Schneider contactor, or a 140M with a non-Allen-Bradley contactor, places the coordination responsibility entirely on the specifying engineer, who must obtain and validate the relevant test data or engineering analysis. For series production panels, mixing brands across protection and switching devices adds significant documentation and validation burden.

How do I verify that my substitute is approved for my installation?

Check the approval markings on the specific catalog number's datasheet against the installation's jurisdiction and project standards. Key markers to confirm include IEC standard compliance, UL motor protection listing category (where UL is required), CSA certification (where Canadian standards apply), and the specific voltage and current ratings listed for each approval. Do not assume that because a product family carries UL or CSA marking, every catalog number within that family is listed — approval scope can vary by variant. If in doubt, consult the manufacturer's approval documentation or contact a sourcing specialist who can pull the specific certification data for the catalog number in question.

  • TeSys GV2L Magnetic Motor Starters are magnetic-only and require a separate external overload relay; they are not a direct GV2ME substitute without adding protection elements to the circuit.
  • Cross-brand equivalents: Allen-Bradley Bulletin 140M (AB ecosystem), Siemens SIRIUS 3RV2 (Siemens ecosystem), Eaton Motor Protective Circuit Breakers PKZM0 / PKE (Eaton ecosystem), ABB Manual Motor Starters MS116 / MS132 (ABB ecosystem).
  • Cross-brand migration effort is consistently high — mechanical dimensions, accessory systems, coordination tables, and approval documentation all require re-verification at the catalog-number level.
  • Short-circuit ratings, current ranges, and approval markings are variant-specific across all series; engineers must consult the exact catalog number's datasheet — series-level data is not sufficient for substitution decisions.
