The 690 V rating (7.5 kA) is lower but still covers the majority of 690 V motor branch faults. Rated current holds at 50 A from 40 °C through 50 °C, then steps down: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, 45 A at 70 °C. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — fits standard 3-pole MCCB panel cutouts. ## Auxiliary contacts and release options The TM210 release is the standard thermal-magnetic type; no ground-fault monitoring or undervoltage release on this order code.","metaTitle":"Siemens 3VA1050-3ED36-0AD0 SENTRON MCCB, 50A, 75.6kA","metaDescription":"Siemens 3VA1050-3ED36-0AD0 SENTRON molded case circuit breaker, 50A rated, 75.6kA breaking at 240V. 3-pole, TM210 release, IP40 front.
