Schneider Electric GVAD1010 TeSys Deca Auxiliary Contact Block (1 NO + 1 NO Fault Signaling): Specifications, Compatibility, and Procurement Guide

Controls engineers and panel builders specifying auxiliary signaling for TeSys GV motor circuit breakers arrive at the same decision point: which contact block variant fits the breaker, the control voltage, and the mounting orientation available in the enclosure. The Schneider Electric GVAD1010 is a side-mounted auxiliary contact block that adds two independent normally open contacts to GV2 and GV3 series motor circuit breakers — one for instantaneous status signaling and one dedicated to fault detection — rated at 6 A across a wide control voltage range of 48–690 V AC or 24–240 V DC. It is a compact, certified solution that eliminates the need for separate relay modules when motor monitoring is required in an existing TeSys GV architecture.

Who Should Buy the GVAD1010 — and Who Shouldn't

The GVAD1010 is the correct choice for engineers and technicians who meet all of the following criteria:

  • Your base motor circuit breaker is a confirmed GV2L, GV2LE, GV2ME, GV2P, GV2RT, GV3L, or GV3P — no other breaker families accept this block
  • The breaker has an unoccupied left-side auxiliary contact slot — physically verified on the installed unit or confirmed in the breaker datasheet
  • Your control circuit operates within 48–690 V AC or 24–240 V DC and your auxiliary contact load does not exceed 6 A per contact
  • You require two normally open contacts: one for instantaneous breaker status and one for isolated fault signaling — not a normally closed output
  • Your wiring practice uses screw clamp termination and control wiring compatible with that terminal style
  • Your application requires UL Listed, CSA Certified, and IEC Certified compliance for North American or international installation

If your breaker has only a right-side mounting slot, look at the GVAD1002. If your control logic requires a normally closed contact in the fault circuit, the GVAD1001 (1 NO + 1 NC) is the correct variant. Installations on Compact NSX, C120, or any non-GV TeSys family require a different product family entirely.

What the GVAD1010 Actually Does in a Motor Control System

Most motor circuit breakers in a TeSys GV installation perform their primary job — overcurrent protection and motor isolation — without any external signal reaching the control system. The breaker trips, but the PLC sees nothing. That gap is exactly what the GVAD1010 closes. It snaps onto the left-side mounting slot of a GV2 or GV3 breaker and adds two electrically independent normally open contact outputs that the control circuit can monitor continuously.

The first contact is instantaneous: it reflects the real-time open or closed state of the breaker. The second is a dedicated fault contact that changes state specifically when the breaker has tripped on a fault condition — overload, short circuit, or manual trip. These two outputs are functionally separate, which matters in automation logic. An instantaneous auxiliary contact tells the PLC the breaker is open; the fault contact tells it why. That distinction drives different downstream actions — a status change might simply illuminate a panel lamp, while a fault signal can initiate an alarm sequence, prevent a downstream motor from starting, or log a maintenance event in an industrial IoT platform.

The GVAD1010 is rated for 100,000 operating cycles, which at five actuations per week equates to roughly 20 years of service life in a typical industrial motor control application. Its 240 W wattage rating and 6 A contact rating per channel accommodate standard control relay coils, PLC digital input modules drawing 24 V DC, and AC annunciator circuits at industrial voltages without requiring an interposing relay in most configurations.

Typical System Architecture for the GVAD1010

The GVAD1010 sits between the GV motor circuit breaker and the automation control layer, converting mechanical breaker state into discrete electrical signals the control system can process.

  • PLC or DCS controller — monitors auxiliary and fault contact states via digital input module
  • Control power transformer — steps line voltage down to control circuit voltage within the 48–690 V AC or 24–240 V DC range accepted by the GVAD1010 contacts
  • GV2 or GV3 motor circuit breaker — host device; GVAD1010 mounts to its left-side auxiliary slot and derives mechanical contact state from breaker position
  • GVAD1010 auxiliary contact block — provides instantaneous NO output to PLC input channel and fault NO output to separate alarm or interlock circuit
  • Downstream devices — alarm horn, strobe light, relay coil, or sequential motor starter interlock wired to the respective contact outputs

Where Engineers Deploy the GVAD1010

In food and beverage production lines, the GVAD1010 fault contact is commonly wired to a PLC input that triggers a line-stop sequence when a motor circuit breaker trips on overload, preventing downstream conveyors from running unattended against a stopped upstream motor. The instantaneous auxiliary contact simultaneously drives a panel indication lamp so operators know which breaker tripped without opening the enclosure.

In wastewater treatment pump stations, the fault contact feeds into a SCADA system that alerts operators remotely when a pump motor breaker faults. This is especially valuable in unmanned remote stations where a tripped motor could go undetected for hours without an automated alarm signal routed through the auxiliary contact.

Pharmaceutical and continuous process facilities use the GVAD1010 fault contact as part of emergency shutdown verification logic. During an E-stop event, the control system confirms that the motor circuit breaker has physically tripped — not merely that the contactor has dropped out — providing a secondary confirmation layer that satisfies process safety requirements.

Panel builders standardizing on TeSys GV architecture for OEM machine builds rely on the GVAD1010 to add CSA- and UL-certified monitoring capability to GV2 breakers without increasing panel footprint significantly. At 9.3 mm wide, the block adds negligible width to the breaker assembly.

Application Typical Deployment
Motor overload alarm annunciation Fault contact drives horn and strobe; PLC input logs event timestamp
Sequential motor interlock Fault contact prevents downstream motor start if upstream GV2 has faulted
Remote pump station monitoring Auxiliary contact wired to RTU digital input; SCADA receives breaker status signal
E-stop shutdown verification Fault contact confirms physical breaker trip to safety relay or PLC safety input
Predictive maintenance logging Fault contact actuation count tracked by PLC for maintenance scheduling
OEM machine builder panels GVAD1010 added to GV2ME or GV2P during build for certified motor monitoring

Expert Verdict: Is the GVAD1010 the Right Part for Your Build?

For panel builders and automation technicians already working within the TeSys GV ecosystem, the GVAD1010 is the obvious selection when motor fault signaling and status monitoring are required. It integrates directly with seven proven GV breaker models — GV2L, GV2LE, GV2ME, GV2P, GV2RT, GV3L, and GV3P — without requiring auxiliary relay modules, additional DIN rail space, or extra wiring runs that a standalone relay approach demands. The dual normally open contact configuration covers the two most common control circuit requirements simultaneously: a continuous status signal and an isolated fault output. Its 100,000-cycle rating and UL, CSA, and IEC certifications make it appropriate for high-duty industrial environments in food, pharmaceutical, and continuous process industries where compliance documentation is a project requirement, not an afterthought. At 9.3 mm wide, it adds almost nothing to enclosure width, which matters in tight panel layouts.

The GVAD1010 is not the right part in three situations worth naming plainly. If the breaker has only a right-side slot, the GVAD1002 is the physically compatible alternative. If your interlock logic depends on a normally closed contact — where the circuit must be energized at rest and drop out on fault — the GVAD1001 (1 NO + 1 NC) matches that logic correctly; ordering the GVAD1010 in its place will produce inverted fault behavior that can be difficult to diagnose in the field. And if the installation does not use a GV2 or GV3 series breaker at all — Compact NSX, C120, or any non-TeSys GV family — the GVAD1010 has no compatible mounting interface and cannot be used regardless of how the control logic is written.

From a procurement standpoint, the GVAD1010 is a well-stocked accessory at authorized Schneider Electric distributors under normal market conditions, and its combination of low unit cost and elimination of separate relay components typically makes it the most cost-effective monitoring solution for GV-based panels. Ordering through a specialist automation distributor — rather than a generic electrical supply channel — provides the application verification step that catches mounting orientation and variant errors before they become field rework.

What Engineers Need to Know Before Ordering the GVAD1010

Because community discussion of the GVAD1010 specifically is sparse in automation forums, the most useful guidance comes from the patterns specialists at industrial automation distributors observe repeatedly across orders. The GVAD1010 is a short catalog number that differs from its siblings by only two digits — and those two digits determine contact polarity, mounting side, and control logic behavior. The ordering mistakes that generate the most field rework are not random; they cluster around three failure modes that are entirely avoidable with a brief pre-order verification process.

The most frequent issue is variant confusion between GVAD1010 and GVAD1001. Both are left-side mount, both fit the same breaker family, and both carry similar pricing. The difference — 2 NO versus 1 NO + 1 NC — only becomes apparent when the installed block produces alarm logic that operates in reverse. An alarm that energizes at rest and drops on fault is not an annunciator; it is a persistent false trip condition that can shut down a production line. The second most common issue is discovering that the installed or specified breaker does not have a left-side slot at all, either because the breaker revision predates that feature or because the slot is already occupied by an earlier auxiliary block installation. Neither situation is recoverable without either replacing the breaker or switching to the right-side GVAD1002 variant.

When community data is limited for a specific part, a brief conversation with a specialist distributor who handles TeSys GV orders regularly is the most reliable substitute. Distributors who work with this product family daily can confirm mounting slot availability for a given breaker model number, identify whether the breaker already ships with integrated contacts that would conflict with an add-on block, and flag control voltage concerns before the order is placed. LeadTime.ca provides exactly that application-level review at no cost as part of the ordering process — which is why engineers specifying TeSys accessories for the first time on a given breaker model benefit from contacting the team rather than ordering blind from a generic catalog search.

Wiring and Installation Overview

The following is an installation overview only. Engineers performing physical installation must follow Schneider Electric's published installation instructions for the GVAD1010 and applicable electrical safety codes (OSHA, CSA, NFPA 79, or IEC 61439-1) for their jurisdiction. Lockout/tagout procedures must be applied before any work begins on the breaker or control circuit.

  • De-energize and LOTO the GV breaker before touching the auxiliary contact slot; confirm zero energy with a calibrated voltage tester before proceeding
  • Locate the left-side mounting slot on the GV2 or GV3 breaker, remove any dust cap, align the GVAD1010 connector tabs, and seat the block firmly until it is flush with the breaker housing — do not force if resistance is encountered; recheck alignment
  • Screw clamp terminals accept control wiring sized for your circuit; strip approximately 6 mm of insulation, insert the wire fully into the terminal, and tighten the screw until the wire is firmly gripped without crushing the conductor
  • Wire the instantaneous NO contact to its designated PLC digital input or status indication circuit; wire the fault NO contact to a separate PLC input or independent alarm relay — do not share a single input across both contacts
  • After restoring power, test by manually tripping the breaker and confirming both contact outputs change state; verify contact return to initial state on breaker reset and repeat the test three times before signing off on the installation

Compatible Breaker Models for the GVAD1010

The GVAD1010 integrates with the following GV series motor circuit breakers. Compatibility requires a physically accessible and unoccupied left-side auxiliary contact slot on the breaker in question.

  • GV2L — Standard GV2 series, left-side slot confirmed; typical industrial motor protection application
  • GV2LE — Enhanced protection variant of GV2; left-side slot available
  • GV2ME — Multifunction GV2 variant; left-side slot available
  • GV2P — Plug-in GV2 variant; left-side slot available
  • GV2RT — Rotary handle GV2 variant; left-side slot available
  • GV3L — Larger frame GV3 series; left-side slot available
  • GV3P — GV3 plug-in variant; left-side slot available

The GVAD1010 is not compatible with Compact NSX100–250, C120, or any other TeSys family outside the GV2 and GV3 series. These breakers use different mounting interfaces and terminal architectures that are physically incompatible with the GVAD auxiliary contact block design.

Wrong-Part Prevention Checklist Before You Order

Before submitting a purchase order for the GVAD1010, verify every item on this checklist. Each point corresponds to a real ordering or installation failure that generates rework and delays. Do not abbreviate or skip items.

  1. Confirm base motor circuit breaker model is GV2 or GV3 series — GVAD1010 will not fit Compact NSX, C120, or other TeSys families
  2. Verify breaker has open auxiliary contact slot on left side; confirm left-side mounting orientation matches control panel layout
  3. Check that control circuit voltage is within 48–690 V AC or 24–240 V DC range
  4. Confirm screw clamp termination is acceptable for your wiring gauge and termination practice
  5. Verify amperage of auxiliary contact requirement does not exceed 6 A per contact
  6. Ensure breaker model is not already equipped with integrated auxiliary contacts that would conflict with block installation

If you have completed this checklist and confirmed the GVAD1010 meets every criterion, place your order or request a quote at LeadTime.ca. If any item raises uncertainty, contact the LeadTime.ca team for application verification before ordering — it is faster than a return shipment.

Frequently Asked Questions

Can I install a second GVAD block on the same GV2 breaker if I need more contact outputs?

The GV2 and GV3 series breakers provide a left-side and, depending on the variant, a right-side auxiliary contact slot. The GVAD1010 occupies the left-side slot only. If you need additional contact outputs beyond what the GVAD1010 provides, the right-side slot can accept a compatible right-side mount variant such as the GVAD1002. Stacking two identical GVAD1010 units on the same side is not possible — only one block can occupy each mounting slot.

Does the fault contact operate with a time delay, or is it instantaneous?

The fault signaling contact on the GVAD1010 is instantaneous — no delay is specified by Schneider Electric in the product datasheet. When the GV breaker trips on overload or short circuit, the fault NO contact changes state without an intentional built-in delay. If your control logic requires a time-delayed fault signal, that delay must be implemented in the PLC program or an external timing relay downstream of the GVAD1010 output.

Can I connect 480 V three-phase line voltage directly to the GVAD1010 auxiliary contact terminals for status signaling?

The GVAD1010 contact rating covers 48–690 V AC, so the voltage level is within the electrical specification. However, best practice per NFPA 79 and IEC 61439-1 for industrial control circuit design is to use a control power transformer to reduce line voltage to a safe control voltage — typically 120 V AC single-phase — for auxiliary contact circuits, alarm devices, and PLC inputs. Applying three-phase line voltage directly across auxiliary contact circuits without a control transformer creates shock hazard conditions and is inconsistent with standard industrial control panel design practice. Review your applicable electrical code and control circuit design standard before making this connection.

Is the GVAD1010 suitable for 24 V DC PLC digital input circuits in a battery-backed or DC control system?

Yes. The GVAD1010 DC voltage rating of 24–240 V DC covers the 24 V DC supply voltage used by the vast majority of PLC digital input modules in industrial automation. The 6 A contact rating per channel is well above the current draw of a standard PLC digital input, which typically draws milliamps at 24 V DC. No interposing relay is required in most 24 V DC PLC input applications. Verify your specific PLC input module's current sink or source requirement against the contact rating before finalizing the circuit.

Is the GVAD1010 a direct drop-in replacement if I need to swap a failed auxiliary contact block on an existing installation?

If the existing installation already uses a GVAD1010 on a compatible GV2 or GV3 breaker with the left-side slot, replacing it with a new GVAD1010 is a straightforward swap — same physical interface, same terminal positions, same contact configuration. Before assuming direct replacement, confirm the model number on the failed unit matches GVAD1010 exactly. A GVAD1001 or GVAD1002 in the same slot will have different contact polarity or mounting orientation and will require control circuit modifications to restore correct behavior.
