Schneider Electric GV4P03N TeSys GV4 3P 3.5 A 50 kA Thermal-Magnetic Motor Protection Circuit Breaker (MPCB)

The Schneider Electric GV4P03N is a TeSys GV4 motor circuit breaker rated 3.5 A at 690 V AC, combining adjustable thermal protection (Ir 1.4-3.5 A) with fixed short-time-delay, phase-unbalance and ground-fault protection for 3-phase motors up to 0.55-1.5 kW at 400 V. Breaking capacity reaches 50 kA at 400 V, and it is operated by a rotary handle via EverLink BTR screw terminals.

Selection Notes

Pick the 3.5 A frame for motors up to 0.55-1.5 kW at 400 V; unlike the magnetic-only GV4L/GV4LE breakers, the GV4P's adjustable thermal dial (Ir 1.4-3.5 A) and built-in short-time-delay, phase-unbalance and ground-fault protection complete motor protection without a separate overload relay. This N-suffix variant carries the full 50 kA breaking capacity at 400 V, versus 25 kA on the identically rated B-suffix variant in the same frame.
