50 A motor branch circuit protection with dual trip technology
The GV4PEM50B: Phase failure sensitivity per IEC 60947-4-1 is built in — the breaker trips on loss of one phase, preventing single-phase motor burnout. Suitability for isolation per IEC 60947-1 means this device can serve as a disconnecting means in the motor branch, eliminating a separate disconnect switch.
Breaking capacity and voltage selection
Under UL 60947, it delivers 35 kA at 240 V and 18 kA at 480Y/277 V. Motor power ratings span 11 kW at 400 V to 45 kW at 690 V, with multiple intermediate steps — confirm the kW column for your supply voltage before specifying.
Panel fit and environmental ratings
Dimensions are 3.2 in wide, 6.1 in high, 4.6 in deep (81 × 155 × 116 mm) — fits standard motor control center buckets and DIN-rail enclosures. IP40 protection suits clean indoor panels; IK07 impact rating resists incidental tool strikes. Operating altitude up to 5000 m without derating, and any mounting position is allowed — useful for tight enclosures where vertical orientation isn't possible. EverLink BTR screw terminals accept up to 95 mm² solid on the bottom and 70 mm² flexible on top — torque to 9 N·m for the main conductors.
