Schneider Electric GV3P50 Motor Circuit Breaker

Schneider Electric GV3P50 is a 3-pole thermal-magnetic motor circuit breaker in the TeSys GV3 family, designed for industrial motor control and manual motor operation. It provides overload and short-circuit protection for three-phase motors in applications such as motor starters, conveyors, pumps, HVAC equipment, and other machinery where reliable motor protection and isolation are required. The device features an adjustable current range of 37–50 A and a rated operational voltage up to 690 VAC, with a thermal-magnetic trip unit suited for AC-3 motor-control duty. Its breaking capacity reaches up to 50 kA at 400–440 VAC, and the magnetic trip current is around 700 A, ensuring fast fault interruption. The GV3P50 uses a rotary handle control, mounts on DIN rail or panel, and utilizes screw clamp (EverLink) terminals for secure connections. Protection features include overload, short-circuit, and phase failure to safeguard both motors and electrical circuits. This model is commonly used for motor protection and manual control within industrial automation, and it sits alongside other GV3 replacements such as GV3P65, GV3ME50, and GV3P40.
