Schneider Electric GV2AF3 TeSys interconnection block three-pole screw-terminal for GV2 motor circuit breaker to LC1D contactor assembly

Schneider Electric GV2AF3 TeSys Interconnection Block / Combination Block with Contactor LC1D09-D38: Specifications, Compatibility, and Installation Overview

If you are assembling a TeSys GV2 motor starter stack and need to connect a GV2 motor circuit breaker to an LC1D09-D38 contactor, the Schneider Electric GV2AF3 is the specific interconnection block that makes that assembly work cleanly and correctly. It is a three-pole, screw-terminal connection block with a 44.5mm device width, designed exclusively for vertical-stacking TeSys modular configurations. The single decision point before ordering: confirm your contactor nameplate shows a size suffix between D09 and D38 — if it reads D65 or higher, you need a different part entirely.

Who Should Buy the GV2AF3 — and Who Should Not

The GV2AF3 is the correct choice for engineers and technicians building or retrofitting motor starter assemblies using the Schneider Electric TeSys modular platform. It is right for you if all of the following apply:

  • Your motor circuit breaker is from the TeSys GV2 family — GV2P, GV2ME, or GV2L variants specifically
  • Your contactor is in the LC1D range with a size suffix from D09 through D38 (LC1D09, LC1D12, LC1D18, LC1D25, LC1D32, or LC1D38)
  • Your TeSys module measures exactly 44.5mm wide — the standard TeSys width, not the 63mm extended or 35mm narrow variants
  • Your assembly is a vertical stacking layout — devices mounted one directly above the other, not side-by-side horizontal
  • Your GV2 device uses screw terminals, not spring push-in terminals

If your contactor is LC1D65 or larger, GV2AF3 will not fit — you need GV2AF2. If your contactor range is strictly LC1D09 through LC1D18 and cost is a factor, GV2AF1 covers that narrower range. Contact your distributor with your contactor nameplate number if you are uncertain which variant applies.

What the GV2AF3 Does in a Motor Starter Assembly

The GV2AF3 is a passive interconnection block — it does not switch, protect, or regulate current. Its job is to provide a clean, pre-engineered mechanical and electrical interface between a TeSys GV2 motor circuit breaker and an LC1D09-D38 contactor in a vertically stacked modular assembly. Without it, you are hand-wiring three-phase connections between two separate devices, which introduces the risk of terminal misalignment, incorrect phase sequencing, and inconsistent conductor sizing across assemblies.

The block carries three poles through screw terminals, accepts conductors sized to coordinate with the upstream GV2 breaker rating, and passes the signal directly to the corresponding main terminals on the downstream LC1D contactor. It weighs just 0.016 kg and adds no active electrical function — its value is purely in standardizing the connection interface and reducing assembly time and error rate across multi-motor control cabinets. Schneider Electric positions it explicitly as a component that simplifies motor starter wiring and provides a consistent, modern appearance across all TeSys modular stacks.

One important boundary to understand: the GV2AF3 has no auxiliary or control terminals. It handles main circuit connections only. Any control wiring for the contactor coil, overload signal, or auxiliary contacts must be handled separately through the contactor and GV2 device's own terminals.

Where the GV2AF3 Sits in Your Motor Control Stack

The GV2AF3 occupies the middle position in a three-device vertical TeSys modular stack, acting as the electrical handoff point between motor protection and switching. The typical component chain runs as follows:

  • Upstream supply (three-phase L1, L2, L3) feeds into the TeSys GV2 motor circuit breaker at the top of the stack
  • The GV2 breaker provides thermal-magnetic protection; its output terminals connect directly to the GV2AF3 input terminals
  • The GV2AF3 passes the three phases through its screw-terminal block, maintaining phase sequence alignment (L1→L2→L3)
  • The GV2AF3 output terminals connect to the main input terminals of the LC1D09-D38 contactor positioned directly below
  • The contactor output (T1, T2, T3) then feeds the motor supply — completing the motor starter signal chain from line supply to motor terminals

Typical Applications and Deployment Scenarios

The GV2AF3 appears most frequently in manufacturing facility automation panels where multiple TeSys motor starter stacks are assembled in a common enclosure. In these environments, the ability to use a pre-engineered connection block across every starter — rather than custom-wiring each one — directly reduces panel build time and creates a consistent assembly that maintenance technicians can troubleshoot without referring back to individual wiring diagrams.

HVAC and pump/fan motor control applications are another high-volume use case. These installations often use LC1D09 through LC1D38 contactors precisely because the motor loads fall within the 9A–38A range that contactor family covers. The GV2AF3 fits into this application without modification, making it a natural BOM item for HVAC panel builders.

Machine tool installations and conveyor system controls also regularly specify GV2AF3 as part of a standardized TeSys starter kit. OEM machine builders in particular benefit from the part number stability of the GV2AF3 — EAN 3389110569063 has been consistent across all Schneider Electric regional domains, indicating a long-established SKU that will not introduce supply disruption mid-production run.

Remote facility upgrades are a fourth common scenario. When a facility manager wants to deploy a consistent motor control architecture across multiple plants — replacing legacy electromechanical overload relay stacks — the TeSys GV2 platform with GV2AF3 interconnection blocks provides a repeatable, standardizable assembly that local electricians at each site can replicate without custom engineering at each location.

GV2AF3 vs. GV2AF1 vs. GV2AF2: Which One Do You Actually Need?

The three GV2AF variants serve the same functional role but cover different contactor size ranges. Ordering the wrong one is the most common sourcing mistake with this product family — the part numbers are close enough that they are easy to mix up in a BOM without checking the contactor size column.

Model Compatible Contactor Range Device Width Assembly Type Terminal Type
GV2AF1 LC1D09 through LC1D18 only 44.5mm Vertical stacking Screw terminal
GV2AF3 LC1D09 through LC1D38 44.5mm Vertical stacking Screw terminal
GV2AF2 LC1D65 and larger (extended range) 63mm Vertical stacking Screw terminal

The rule is simple: if your contactor nameplate reads LC1D25, LC1D32, or LC1D38, GV2AF3 is correct and GV2AF1 is not. If your contactor is LC1D65 or larger, neither GV2AF1 nor GV2AF3 will fit — GV2AF2 is the correct choice and it uses a 63mm device width, so your GV2 breaker must also be the 63mm wide variant. Verify your contactor nameplate and your device width measurement before placing any order. Check current availability for the GV2AF3 at LeadTime.ca — and if you need the GV2AF1 or GV2AF2 instead, contact us with your contactor model number and we will confirm the correct part.

Expert Verdict: Is the GV2AF3 Worth Specifying?

The GV2AF3 is the right specification for any controls engineer or panel builder who is already working within the Schneider Electric TeSys GV2 and LC1D platform. Its value is not in any single electrical capability — it is a passive component — but in what it eliminates: the need to source, size, and hand-wire individual terminal blocks between a motor circuit breaker and its contactor in a three-phase motor starter stack. The pre-engineered three-pole interface ensures phase alignment is correct by design, not by individual judgment on each assembly. For OEM machine builders building identical panels in volume, for integrators retrofitting multiple motor circuits with modern TeSys protection, and for facility maintenance teams who need consistent spare-part logic across sites, GV2AF3 reduces both assembly time and the risk of a wiring error making it to site commissioning.

The limits of this part are equally clear. If your contactor is outside the LC1D09-D38 range — specifically if you are working with LC1D65 or larger — GV2AF3 will not physically mate with your stack and GV2AF2 is the correct substitution. If your installation layout is horizontal rather than vertical, this block is not designed for that configuration and forcing it will risk damage to the screw terminals. If your GV2 device carries spring push-in terminals rather than screw terminals, the interface is incompatible. None of these are edge cases — they are the three most common ordering mistakes documented with this product family, and each one results in a return shipment and project delay that easily costs more than the part itself.

From a procurement standpoint, GV2AF3 is a well-established, commodity-level accessory with EAN 3389110569063 confirmed stable across all Schneider Electric regional domains. Typical lead times from authorized distributors run two to three business days from stock for single-unit orders. For teams building multiple TeSys starter assemblies, ordering GV2AF3 alongside the GV2 breaker and LC1D contactor as a bundled kit — rather than sourcing the connection block separately as an afterthought — is the faster and lower-risk procurement path.

What Engineers Need to Know Before Ordering the GV2AF3

Because the GV2AF3 sits within a tightly defined compatibility envelope — specific motor circuit breaker family, specific contactor range, specific device width, specific terminal type, and specific mounting orientation — it is a part where specialist pre-order verification consistently prevents returns. The three GV2AF variants share a near-identical appearance and similar part numbers, and the difference between a correct order and an incompatible one comes down to a two-digit suffix on the contactor nameplate. The following observations reflect the most common specification and ordering errors associated with this product type.

The most frequently reported ordering mistake is confusing GV2AF1 with GV2AF3. The GV2AF1 covers only LC1D09 through LC1D18. Engineers with an LC1D32 or LC1D38 in their starter assembly who order GV2AF1 — sometimes because it appears first in a search result or because the price difference draws attention — receive a block that will not mechanically align with their contactor. The return and re-order cycle typically adds two to three business days to project commissioning, plus the cost of return shipping and re-inspection labor. The prevention is straightforward: read the contactor nameplate, identify the size suffix (D09, D18, D25, D32, D38), and cross-reference against the variant table above before adding to cart.

The second significant specification risk is layout assumption. Some panel assemblers assume the GV2AF3 can be adapted for horizontal side-by-side device arrangements. It cannot. The block is engineered for vertical stacking — one device directly above the next in a TeSys modular column. Attempting to use it in a horizontal DIN-rail layout misaligns the terminal interfaces and risks terminal damage on both the connection block and the adjacent devices. If your enclosure layout requires horizontal device placement, the solution is individual terminal blocks with hand wiring, not a modified use of GV2AF3. Confirm your assembly orientation before specifying this part in the BOM.

A third area where specialist distributor advice adds real value is bundle confirmation. The GV2AF3 is one component in a four-part motor starter assembly: GV2 motor circuit breaker, GV2AF3 interconnection block, LC1D contactor, and overload relay. Engineers ordering from a general supplier will receive the part they asked for. Engineers ordering through a specialist industrial distributor like LeadTime.ca can confirm all four parts are compatible, currently in stock, and sized correctly for the motor load before the order ships — eliminating the most expensive class of mistake, which is discovering an incompatibility on the panel shop floor.

Wiring and Installation Overview

The GV2AF3 installation is straightforward when the three-device vertical stack is correctly assembled. The following points cover the key requirements and verification steps — for full wiring diagrams and detailed torque specifications, refer to the Schneider Electric TeSys GV2 installation documentation.

  • De-energize and lock out all circuits before assembly. Position the GV2 motor circuit breaker at the top of the stack, the GV2AF3 directly below it, and the LC1D contactor directly below the connection block — verify vertical alignment of all three devices before securing.
  • Insert incoming supply conductors (L1, L2, L3) into the corresponding input terminals of the GV2AF3. Maintain phase sequence throughout — L1 to terminal 1, L2 to terminal 2, L3 to terminal 3.
  • Connect the GV2AF3 output terminals (M1, M2, M3) to the corresponding main input terminals on the LC1D contactor. Tighten all screw terminals to the torque specification listed in the manufacturer documentation — do not over-tighten, as this can damage the screw terminal threads in the block body.
  • Verify conductor sizing is coordinated with the upstream GV2 motor circuit breaker current rating — undersized conductors through the connection block can cause thermal issues under sustained load.
  • After assembly, verify phase sequence before energization and apply permanent identification labels to all conductor connections and device terminals.

Wrong-Part Prevention Checklist

Before placing your order, work through the following checklist verbatim. Each item corresponds to a documented incompatibility that results in returns, project delays, or installation damage.

  1. Verify your motor circuit breaker is from the TeSys GV2 family (GV2P, GV2ME, not GV3, GV4, or GV5)
  2. Confirm your contactor model falls between LC1D09 and LC1D38 (check contactor nameplate)
  3. Measure device width — must be exactly 44.5mm (standard width, not narrow or wide variants)
  4. Check terminal type — this block is for screw terminals only (not spring terminals)
  5. Confirm vertical stacking layout (not horizontal side-by-side arrangement)
  6. Verify you are not using a DIN-rail mounted contactor instead of TeSys modular stack
  7. Check that you have not confused this with GV2AF1 or GV2AF2 (different contactor ranges)

If any item on this checklist fails, do not order GV2AF3. Contact the LeadTime.ca team with your GV2 model number and contactor nameplate — we will confirm the correct part before your order ships.

Frequently Asked Questions

My contactor is an LC1D32. Does the GV2AF3 cover it, or do I need GV2AF1?

GV2AF3 covers LC1D09 through LC1D38, which includes LC1D32. GV2AF1 covers only LC1D09 through LC1D18 — it will not mate correctly with an LC1D32. GV2AF3 is the correct part for your application.

Can the GV2AF3 be used with a GV3 or GV4 motor circuit breaker?

No. The GV2AF3 is compatible only with TeSys GV2 family devices — GV2P, GV2ME, and GV2L variants. GV3 and GV4 motor circuit breakers have different form factors and terminal interfaces. Using GV2AF3 with a GV3 or GV4 will result in mechanical misalignment and cannot be safely adapted.

Is the GV2AF3 suitable for a horizontal DIN-rail layout where the GV2 and LC1D are mounted side by side?

No. The GV2AF3 is designed exclusively for vertical stacking — devices mounted one directly above the other in the TeSys modular column. Horizontal side-by-side layouts require a different connection method. Attempting to force GV2AF3 into a horizontal layout risks damage to screw terminals and adjacent devices.

My GV2 device has spring push-in terminals instead of screw terminals. Will GV2AF3 work?

No. The GV2AF3 is designed for screw terminal interfaces only. If your GV2 motor circuit breaker variant uses spring push-in terminals, you need the spring-terminal equivalent connection block. Check the device faceplate — screw terminals have visible turning screws, while spring terminals have smooth slot openings with a small release lever. Consult Schneider Electric technical documentation or contact your distributor for the correct spring-terminal connection block part number.

Is the GV2AF3 an active component — does it provide any current limiting or protection?

No. The GV2AF3 is a fully passive component. It carries no active switching, protection, or regulation function. Current-carrying capacity through the block is coordinated with the upstream GV2 motor circuit breaker and the downstream LC1D contactor ratings — the block itself does not limit or protect. All motor protection is provided by the GV2 device; all switching is provided by the LC1D contactor.

What is the typical lead time for GV2AF3, and is it available outside North America?

GV2AF3 is listed as in-stock by multiple authorized distributors across North America, the UK, and EU regions, with typical lead times of two to three business days for single-unit orders from warehouse stock. EAN 3389110569063 has been confirmed consistent across Schneider Electric regional domains in North America, Europe, and Asia-Pacific, indicating stable global availability.
