Thermal derating is published per the datasheet: the breaker holds 50 A from 40 °C through 50 °C, then steps down to 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. The breaker ships with a factory-fitted shunt trip (STL) release (order code 3VA9688-0BL33) and two HQ auxiliary switches, so it arrives ready for remote tripping and status feedback without a separate accessory order. The TM240 release is a fixed thermal-magnetic design — no interchangeable trip unit, no communication module, no phase-failure detection. It is a line-protection breaker, not a motor-protection or ground-fault device. The auxiliary contacts (2 HQ switches) and the shunt trip are integrated at the factory, so no field wiring of separate accessory kits is needed beyond connecting the trip coil circuit.","metaTitle":"SENTRON 3VA1150-4EF36-0KC0 MCCB, 50A, 3-Pole, 121kA at 240V","metaDescription":"SENTRON 3VA1150-4EF36-0KC0 molded case circuit breaker, 50A rated continuous current, 3-pole, TM240 thermal-magnetic release, 121kA breaking capacity at 240V.
