Schneider Electric GV2ME20 TeSys Deca Manual Starter and Protector: Specs, Pricing, and Selection Guide

When a controls engineer or procurement specialist searches for the Schneider Electric GV2ME20, they are typically mid-project: a motor control cabinet is being built or retrofitted, a replacement is urgently needed, or a panel builder is confirming the right part before an RFQ goes out. The GV2ME20 is a 3-pole manual motor starter and protector from the TeSys Deca family, rated for 13 to 18A full-load current and available in voltage variants from 230V AC up to 690V AC. It combines manual pushbutton on/off control with integrated thermal-magnetic circuit protection in a compact enclosure measuring 1.77 in x 3.08 in x 3.5 in — eliminating the need for a separate contactor and overload relay in many fixed-speed motor applications.

If you have already confirmed this is the correct model for your motor, check current pricing and availability for the GV2ME20 at LeadTime.ca — we ship worldwide.

Who Should Buy the GV2ME20 — and Who Shouldn't

The GV2ME20 is the right choice for engineers and technicians working with fixed-speed 3-phase AC motors where local manual control and integrated protection are both required in a single compact unit. Choose this model if all of the following apply to your application:

  • Motor is 3-phase AC (not single-phase or DC)
  • Motor full-load current falls within the 13 to 18A band — confirmed from the motor nameplate
  • Application voltage matches one of the available GV2ME20 ratings: 230V, 400V, 415V, 440V, 600V, or 690V AC
  • Manual pushbutton (local operator) control is acceptable — no remote or PLC-driven electric actuation required
  • Motor operates in one direction only — non-reversing design is a hard constraint of this model
  • Application runs at fixed speed — no VFD, soft-start, or variable speed control in the circuit

If your motor exceeds 18A full-load current, step up to the GV2ME32 (25–32A) or GV2ME63 (40–63A). If remote electric actuation is needed, this manual starter is not the correct device — specify an electric contactor with an overload relay instead.

What the GV2ME20 Actually Does in a Motor Control Circuit

The GV2ME20 serves two functions simultaneously that would otherwise require two separate devices. As a manual starter, it provides the operator with a local pushbutton to energize and de-energize the motor — no control voltage, no coil, no PLC output required. As a motor circuit protector, it houses both a thermal overload element and a magnetic short-circuit element in the same 3-pole housing.

The thermal element responds to sustained current above the motor's nameplate rating — the kind of slow overheating that occurs when a motor is mechanically overloaded or runs in high-ambient-temperature conditions. The magnetic element responds to instantaneous high-fault current events such as a winding short circuit, tripping within milliseconds to interrupt the fault before damage propagates. Together, these meet the IEC 60947-2 motor circuit-breaker standard and IEC 60947-4-1 non-reversing motor starter standard, and the device carries UL 508 listing under File No. E164864.

The non-reversing mechanical design is a deliberate safety feature, not a limitation to work around. In drive applications where unintended motor reversal could cause mechanical damage or personnel hazard, the GV2ME20's inherent inability to reverse provides a physical safeguard that software interlocks cannot replicate. After any trip event — thermal or magnetic — manual reset is required before the motor can restart, which forces operator intervention and prevents automatic restart into a fault condition.

The device does not replace the main feeder disconnect. It provides motor branch protection only. A correctly sized upstream main disconnect or contactor must already be in the circuit before the GV2ME20 is installed.

Typical System Architecture for the GV2ME20

The GV2ME20 sits in the motor branch circuit between the feeder disconnect and the motor terminals — it is both the switching device and the branch protection element in one housing. Here is where it fits in a typical motor control cabinet:

  • Main feeder disconnect or main circuit breaker (upstream, sized for full motor current and feeder protection)
  • GV2ME20 mounted on DIN rail or threaded cabinet surface — receives 3-phase L1, L2, L3 from upstream
  • GV2ME20 output terminals connect directly to motor power cable (T1, T2, T3)
  • Operator accesses the manual pushbutton on the GV2ME20 face for local start/stop control
  • 3-phase AC motor (fixed speed, non-reversing, 13–18A full-load current) connected at the load end

Where the GV2ME20 Gets Installed: Industries and Use Cases

The GV2ME20 is the workhorse motor starter for small-to-medium 3-phase motor applications across a wide range of industries. In manufacturing and process automation, it controls conveyor drive motors, pump motors, and fan motors where fixed-speed operation is standard and cabinet space is at a premium. Panel builders frequently specify it because the single-unit form factor reduces wiring complexity compared to assembling a separate contactor and overload relay.

Food and beverage processing facilities use the GV2ME20 for wash-down area motor control where compact, cleanable enclosures simplify maintenance. HVAC and building automation integrators apply it to fan coil units and cooling tower motors where local manual control is preferred over building automation system integration for small auxiliary motors.

Replacement applications represent a significant portion of GV2ME20 orders. Plant electricians replacing a worn or tripped starter in an existing Schneider motor control panel find the GV2ME20 familiar and dimensionally compatible within the TeSys family. OEM equipment builders standardize on it across their machine platforms to simplify spare parts inventory and field support.

Application Typical Deployment
Conveyor motor control New build or retrofit MCC panel; manual pushbutton local control; fixed-speed non-reversing drive
Pump motor protection Pump station motor branch protection; replaces separate contactor + overload relay in space-constrained enclosure
HVAC fan motor control Auxiliary fan motor; local operator start/stop; fixed-speed operation at 400/415V or 600V
OEM equipment manufacturer Standard motor control module across machine platform; UL 508 listed; single unit simplifies BOM
Replacement / field swap Direct replacement in existing TeSys GV2 installation; same footprint; no cabinet modification required
Compressor motor protection Small 3-phase compressor motor branch; thermal-magnetic protection for sustained overload and short circuit

GV2ME20 vs GV2ME14 vs GV2ME32 vs GV2ME63: Which Model Do You Need?

Model Current Range Typical Motor Power (400V) When to Choose
GV2ME14 10–14 A Up to 5.5 kW Smaller 3-phase motors with FLC under 14A; step down from GV2ME20
GV2ME20 13–18 A Up to 7.5 kW Standard mid-range selection; most common in this family for small-to-medium 3-phase motors
GV2ME32 25–32 A Up to 11 kW Step up when motor FLC exceeds 18A; requires physical cabinet redesign for larger frame
GV2ME63 40–63 A Up to 30 kW Heavy-duty large 3-phase motors; significant size increase over GV2ME20
Separate Contactor + Overload Relay Flexible 10–63A range Depends on component selection When reversal capability, remote electric actuation, or modular flexibility is required

If your motor full-load current is 19A or higher, the GV2ME20 is not the correct device — check current availability of the full GV2ME series at LeadTime.ca and confirm the next model up before placing your order.

Expert Verdict: Is the GV2ME20 Worth Specifying?

The GV2ME20 is the right specification for controls engineers and panel builders working with fixed-speed 3-phase motors in the 13 to 18A full-load current range who need both manual operator control and integrated motor branch protection in the smallest possible cabinet footprint. OEM equipment manufacturers standardizing on a compact, UL 508-listed, IEC 60947-4-1-compliant motor control module will find this device does exactly what it is supposed to do — transparently and predictably — without requiring firmware, software configuration, or calibration tools. The thermal-magnetic protection mechanism is a proven, field-serviceable design that maintenance technicians understand without specialized training. For retrofit installations, the TeSys Deca form factor and threaded mounting typically drop into existing cabinet cutouts without modification.

Where this device has genuine limits: it is not the right tool for motors above 18A full-load current, applications needing PLC or remote actuation, or any circuit requiring motor reversal. If your design calls for variable speed or soft-start, the GV2ME20 is explicitly not suitable — this is a full-speed, fixed-frequency device only. For those requirements, a separate contactor plus electronic overload relay combination, or a dedicated VFD with integral protection, is the correct path. Be equally precise about voltage: with six voltage variants available — 230V through 690V AC — ordering without explicitly specifying voltage is the single most common specification error on this model and results in a non-functional device in the field.

From a procurement standpoint, the GV2ME20 benefits from broad distributor support and typically carries a 1 to 2 week lead time from major automation distributors. Buying through an authorized Schneider specialist distributor rather than a generic online channel matters here — not for marketing reasons, but because voltage variant confirmation and pre-sale model verification reduce the probability of a costly return. A specialist distributor will verify your voltage and current specification against the motor nameplate data before the order ships.

What Engineers Need to Know Before Ordering the GV2ME20

Because community forum data for this specific model is limited, the most reliable guidance comes from the specification patterns that cause field failures and costly returns on manual motor starters in this class. The GV2ME20 has a straightforward operating principle, but its multi-voltage, multi-current platform creates ordering complexity that is worth addressing before the purchase order is submitted.

The most consequential misunderstanding engineers encounter with this device is treating the model number alone as sufficient ordering information. The catalog number GV2ME20 defines the current band (13–18A) and the product type, but it does not specify voltage. Six distinct voltage ratings — 230V, 400V/415V, 440V, 500V, 600V, and 690V AC — exist within the GV2ME20 product line. Distributors who are not automation specialists may ship the most commonly stocked voltage variant without confirming the application requirement. The result is a device that arrives on site, appears correct, and fails to function because the voltage does not match the motor installation. Explicit voltage documentation in the purchase order is non-negotiable.

A second pattern worth flagging: the overlap zone between GV2ME14 and GV2ME20. The GV2ME14 covers 10 to 14A, and the GV2ME20 covers 13 to 18A — creating a 13 to 14A overlap where either model is technically within range. In that overlap, the general guidance is to select based on whether nuisance tripping is a concern. A motor running consistently near 13A in a warm environment is better served by the GV2ME20, which provides more thermal headroom at that current level. When in doubt in the overlap zone, consult a Schneider-authorized distributor who can review the full motor nameplate data before confirming the model. LeadTime.ca provides exactly this kind of pre-sale technical verification — contact the team before submitting an RFQ if your motor FLC lands in that band.

Wiring and Installation Overview

The following is a brief overview of GV2ME20 installation requirements. For full wiring procedures, refer to the manufacturer's installation manual available from Schneider Electric's technical documentation portal.

  • Mount the GV2ME20 on a DIN rail or threaded cabinet surface using the device's integrated threaded mounting points; ensure mounting is secure and vibration-proof with minimum clearance for pushbutton access
  • Connect incoming 3-phase power (L1, L2, L3) to the screw clamp input terminals; terminal type accepts 0.5–1.5 mm² wire — verify wire gauge against application current before terminating
  • Connect GV2ME20 output terminals to motor power leads (T1, T2, T3) using the same screw clamp procedure; verify no loose strands or cross-connections before energization
  • Confirm upstream main disconnect or feeder circuit breaker is correctly sized and installed — GV2ME20 provides motor branch protection only, not feeder protection; the main disconnect must be present and upstream
  • Operating temperature must remain within -4°F to 140°F; thermal element response changes outside this band and thermal derating per IEC standards is required — confirm ambient conditions before installation if the enclosure operates near these limits

Wrong-Part Prevention Checklist Before You Order

Before submitting a purchase order for the GV2ME20, verify each of the following items against your motor nameplate and application design. This checklist is drawn directly from the most common specification errors on manual motor starters in this class:

  1. Confirm motor is 3-phase AC, not single-phase or DC
  2. Verify motor nameplate full-load current falls within 13–18A band (GV2ME20 rated; lower models like GV2ME14 exist for smaller motors)
  3. Check application voltage against model rating — confirm 690V, 600V, 440V, 415V, 400V, or 230V requirement; GV2ME20 supports multiple ratings
  4. Confirm manual pushbutton operation is required; if remote/electric start needed, this is not the right model
  5. Verify non-reversing (one-direction only) operation acceptable; GV2M prefix indicates non-reversing; do not confuse with reversing TeSys contactors
  6. Check circuit protection upstream — GV2ME20 provides motor protection, not main feeder protection; confirm main disconnect/contactor already specified
  7. Inspect motor power requirement — confirm no soft-start, VFD, or variable speed control required; this device is full-speed only

If any item on this list cannot be confirmed before ordering, contact the LeadTime.ca team — our technical team will verify the correct model selection against your motor data before the order is placed.

Frequently Asked Questions

My motor nameplate shows 14A full-load current — should I order the GV2ME14 or the GV2ME20?

Both models cover 14A since the GV2ME14 runs up to 14A and the GV2ME20 starts at 13A. For motors consistently operating near their rated current or in warm ambient conditions, the GV2ME20 provides more thermal headroom and reduces the likelihood of nuisance thermal trips. If the motor regularly runs well below 14A and the environment is within standard temperature range, the GV2ME14 is a correct fit. When in doubt, confirm with your distributor by providing the full motor nameplate data — current, voltage, power factor, and service factor.

Can the GV2ME20 be used on a circuit with a variable frequency drive (VFD)?

No. The GV2ME20 is designed for fixed-frequency 3-phase AC motors running at line voltage. It is not suitable for installation on the output side of a VFD, where the waveform characteristics differ from sinusoidal line voltage and thermal-magnetic protection elements will not function correctly. For VFD-driven motors, motor protection must be specified according to VFD manufacturer requirements — typically an electronic overload relay or drive-integrated thermal protection.

What is the interrupt rating of the GV2ME20, and does it vary by voltage?

Yes, interrupt rating varies significantly with voltage. At 230/240V AC, the GV2ME20 is rated for 100 kA short-circuit withstand capacity. At 400/415V AC, the rating is 15 kA. At 440V AC it is 8 kA, at 500V AC it is 6 kA, at 600V AC it drops to 3 kA, and at 690V AC it is also 3 kA. The upstream overcurrent protection must be coordinated with these interrupt ratings — especially in higher-voltage North American 600V installations where the 3 kA rating is the relevant figure.

After a thermal trip, can the GV2ME20 restart automatically, or is manual reset required?

Manual reset is always required after a trip event — thermal or magnetic. This is a deliberate safety design. The device will not automatically re-energize the motor after a trip, which prevents automatic restart into a fault or overload condition. After the thermal element has cooled (typically allow 5 to 10 minutes), the reset button must be pressed manually before the motor can be restarted via the pushbutton. Repeated thermal trips without investigation indicate a persistent overload condition — do not force repeated resets without diagnosing the root cause.

Is the GV2ME20 a direct replacement for an older GV2 series unit in an existing cabinet?

The GV2ME20 is part of the TeSys Deca family within the GV2 series, so it is dimensionally and functionally compatible with existing GV2 motor circuit-breaker installations in most cases. However, always verify the current rating and voltage variant of the existing installed device against the replacement unit before ordering. A GV2 unit of the same model number but different voltage variant is not a functional equivalent — voltage must match.

Does the GV2ME20 need to be derated at high ambient temperatures?

The GV2ME20 is rated for operation between -4°F and 140°F. Within this range, the thermal element functions at its rated characteristics. Above 104°F (40°C), thermal derating applies per IEC standards — the thermal element may respond at a lower current than its nameplate setting, which can cause nuisance trips on motors running near full-load current. If the installation environment exceeds 104°F regularly, verify derating requirements against the Schneider Electric technical documentation or contact an authorized distributor for guidance before specifying this device.
