Schneider GV2-ME22C Retrofit-Ready Motor Protector for TeSys GV2 Control Systems
The Schneider Electric GV2-ME22C is a 20–25A thermal-magnetic motor protection circuit breaker engineered for seamless integration into legacy TeSys GV2 series control panels. Whether you are replacing a discontinued unit, upgrading an aging motor starter assembly, or modernizing a multi-motor control cabinet, the GV2-ME22C delivers drop-in mechanical compatibility, wiring-terminal alignment, and full coordination with existing downstream contactors and overload relays in the TeSys D and TeSys K families.
Industrial facilities running older Schneider automation architectures — including those built around the Modicon M340, Modicon M580, or Modicon Premium PLCs — frequently encounter GV2-series motor breakers that have reached end-of-service life. The GV2-ME22C is the current production equivalent for the 20–25A range, maintaining backward compatibility with standard 45mm DIN rail mounting, front-face terminal access, and the same rotary handle interface used across the GV2 product generation. This makes it the preferred choice for retrofit projects where panel re-engineering time and downtime must be minimized.

Retrofit Planning for Existing Automation Systems
A successful GV2-ME22C retrofit begins well before the panel is de-energized. Engineers should first audit the existing motor starter assembly to confirm the contactor model — typically an LC1-D25 or LC1-D32 — and verify that the downstream overload relay, if separate, is either removed or coordinated with the new breaker’s built-in thermal protection. In many TeSys GV2 assemblies, the motor breaker is mounted directly above the contactor on a GV2-G spacer-connector, which eliminates the need for external wiring between the two devices. Confirm that the spacer-connector is in serviceable condition before reuse.
For panels that include a GV2-AN11 or GV2-AE11 auxiliary contact block, these accessories clip directly onto the GV2-ME22C body without modification, preserving the existing signal wiring to the PLC input card — whether that is a Modicon TM3DI16 discrete input module or a legacy TSX DEY 16D2 input card on a Modicon Premium rack. Verify the auxiliary contact wiring polarity and confirm the PLC program logic references the correct input address before re-energizing.
Power supply capacity is a critical checkpoint. The control cabinet’s 24VDC PHASEO ABL8REM24030 or equivalent power supply must be confirmed to support the coil current of the replacement contactor and any additional I/O modules added during the upgrade. If the retrofit also involves adding a TM3-XTRA1 expansion module or a Modicon TM3AI8 analog input module for motor current monitoring, recalculate the total rail current budget before closing the panel.
For systems communicating over Modbus RTU or CANopen, confirm that the GV2-ME22C’s optional communication gateway — if used — is correctly addressed and that the Modicon M340 or M580 PLC program includes the updated device map. HMI screens built on Magelis HMIGTO or Vijeo Designer platforms should be reviewed to ensure motor status symbols, trip indicators, and reset buttons reference the correct PLC variable addresses after any I/O remapping.
Downtime Control During System Migration
Minimizing production downtime during a GV2-ME22C swap requires a structured hot-swap preparation protocol. Before shutdown, photograph or export the existing terminal wiring layout, record the PLC program’s I/O address table, and confirm that a tested spare GV2-ME22C unit is on-site. Where the motor circuit is part of a redundant drive system — for example, a duty/standby pump pair controlled by a Modicon M580 with a BMXNOE0110 Ethernet module — switch load to the standby circuit before beginning work on the primary starter.
During replacement, transfer auxiliary contact wiring terminal by terminal using the original wiring diagram. Do not rely on color coding alone, as aging insulation may have faded. After mechanical installation, perform a manual trip test using the rotary handle before reconnecting the load circuit. Re-energize the control circuit first, confirm PLC input status, then close the main circuit under no-load conditions before returning the motor to service. This sequence protects both the new GV2-ME22C and the connected motor from inrush faults caused by incorrect wiring.
All units supplied by SMARTNEXMSK are function-tested prior to shipment and include a 12-month warranty covering manufacturing defects. Shipment originates from Xiamen, China, with typical lead times of 3–7 business days for stocked SKUs.
Retrofit Support FAQ
Q1: Is the GV2-ME22C a direct replacement for the discontinued GV2-ME22 and GV2-P22?
Yes. The GV2-ME22C is the current production successor for the 20–25A range within the TeSys GV2 family. It shares the same DIN rail footprint, terminal pitch, and auxiliary contact interface, making it a mechanical and electrical drop-in replacement. No panel modification is required in standard configurations.
Q2: What commissioning checks are required after installation?
After installation, verify the thermal trip class setting matches the motor’s FLA (full-load amperage), perform a manual trip test, confirm auxiliary contact signal continuity to the PLC input, and test the motor under no-load before returning to full production. If a GV2-G spacer-connector is used, inspect the connector pins for oxidation before reuse.
Q3: Can the GV2-ME22C be used with existing LC1-D series contactors and TeSys U assemblies?
Yes. The GV2-ME22C is fully coordinated with LC1-D25 and LC1-D32 contactors for Type 2 coordination per IEC 60947-4-1. It is also compatible with TeSys U base units when used with the appropriate GV2-G spacer-connector. Confirm contactor coil voltage matches the control circuit supply before assembly.
Q4: What does the 12-month warranty cover, and how is it claimed?
The 12-month warranty covers manufacturing defects, premature trip mechanism failure, and terminal connection faults under normal operating conditions. To initiate a warranty claim, contact SMARTNEXMSK with the order number, installation date, and a description of the fault. Replacement units are dispatched after fault verification, with return shipping coordinated by our technical team.
