Breaking capacity runs 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — so the same breaker can serve 240 V branch panels and 400 V motor control centers as long as the available fault current stays under those numbers. No auxiliary contacts, no communication module, no phase-failure detection; it's a plain line-protection MCCB with a UVR coil. The breaker carries 50 A continuously from 40 °C through 50 °C ambient, then derates to 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. Dimensions are 130 mm tall, 101.6 mm wide, 70 mm deep. For frequent switching, look at the 3VA contactor-based motor-protector variants instead.","metaTitle":"Siemens SENTRON 3VA1050-2ED42-0DA0 MCCB, 50 A, 4-Pole, Line","metaDescription":"Siemens SENTRON 3VA1050-2ED42-0DA0 4-pole molded case circuit breaker, 50 A continuous, 52.5 kA at 240 V.
