Undervoltage release (UVR) is built in, so it drops the load if supply voltage falls below the dropout threshold. Footprint is 76.2 mm wide by 130 mm tall by 70 mm deep — a standard 3-pole MCCB envelope. Current derating is flat from 40 °C to 50 °C at 50 A, then drops to 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C.","metaTitle":"Siemens 3VA1150-4EF32-0BH0 SENTRON MCCB, 50 A, 121 kA at 240","metaDescription":"Siemens 3VA1150-4EF32-0BH0 SENTRON molded case circuit breaker, 50 A rated, 121 kA breaking at 240 V.
