Schneider Electric GV4L03N TeSys GV4 3P 3.5 A 50 kA Magnetic Motor Protection Circuit Breaker (MPCB)

The Schneider Electric GV4L03N is a TeSys GV4 motor circuit breaker rated 3.5 A at 690 V AC, giving magnetic-only protection for 3-phase motors up to 0.55-0.75 kW at 400 V; it is paired with a separate class 10 or 20 thermal overload relay to complete motor protection. Its magnetic trip is adjustable from 21-49 A, 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 0.55-0.75 kW at 400 V; because this breaker only trips magnetically, size the accompanying thermal overload relay (class 10 or 20) to the motor's actual full-load current rather than relying on the breaker alone. The 50 kA breaking capacity at 400 V is common across the whole GV4L/GV4LE range, so frame selection is driven purely by current rating.
