The thermal derating from 45 °C to 70 °C is mild: 50 A at 45 °C and 50 °C, 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C — no need to oversize for typical panel ambient up to 50 °C. Width is 101.6 mm (4 in), depth 70 mm (2.76 in), height 130 mm (5.12 in). No integrated communication function or motor drive option — this is a standalone breaker for manual or remote shunt-trip operation.","metaTitle":"Siemens 3VA1050-4ED46-0AA0 SENTRON MCCB, 50 A, 4-Pole, TM210","metaDescription":"Siemens SENTRON 3VA1050-4ED46-0AA0 molded case circuit breaker, 50 A, 4-pole, TM210 release.
