GV2P32 | Motor circuit breaker, TeSys GV2, 3P, 24-32 A, thermal magnetic, screw clamp terminals – Schneider Electric

Q: How do I set the 24–32 A adjustable range on the GV2P32 for my motor?

A: Turn the setting dial to the motor’s nameplate full-load current (FLC) — the FLC must fall within the 24–32 A range of this device. Setting it at the motor FLC (not the maximum of the range) gives correct overload trip timing while still riding through normal starting inrush. If the motor FLC is outside this range, select the adjacent rating in the same series.

Q: What is the trip class of the GV2P32 and what motor starting time does it allow?

A: MPCBs are typically rated Class 10 (trips in ≤10 seconds at 7.2× setting current), suitable for normal motors with DOL starting times up to 10 seconds. Heavy-duty motors (large fans, centrifuges, compressors) with longer starting times may need Class 20 or Class 30 protection — check the starting time against the motor’s speed-torque curve and select accordingly.

Q: Can the GV2P32 replace a contactor + overload relay combination in a motor circuit?

A: The GV2P32 provides motor short-circuit protection and overload protection in one device — but it cannot make/break motor current under normal operational switching (that is the contactor’s role). For motor starters requiring on/off switching, the GV2P32 is used as the upstream protection device with a contactor for switching. Some MPCB series include a direct handle for manual starting of small motors without a separate contactor.

Q: Which Schneider Electric accessories are compatible with the GV2P32?

A: The Schneider Electric GV2P32 series supports snap-on accessories including auxiliary contacts (OF), alarm contacts (SD), shunt trip coils (MX), undervoltage releases (MN), and comb busbars. Accessories are series-specific — always verify compatibility using the Schneider Electric product catalogue before ordering. myelectric.in can advise on the correct accessory part numbers for the GV2P32.

Q: What is the difference between a Motor Protection Circuit Breaker (MPCB) and a standard MCB — and why use the GV2P32?

A: A standard MCB protects against overload and short-circuit only. A Motor Protection Circuit Breaker (MPCB) adds adjustable thermal overload matched to motor FLC, Class 10/20 trip curves for motor starting inrush, and phase-loss sensitivity — making it the correct device for motor branch circuits where a standard MCB would either nuisance-trip on motor starting or fail to protect adequately against slow overloads. Choose the GV2P32 when the application specifically requires motor protection circuit breaker (mpcb) characteristics.
