At 415 V the breaking capacity drops to 32 kA, and at 690 V it's 7.5 kA, so the voltage you're coordinating against determines the available fault current this breaker can handle. ## Thermal derating and continuous current Above that it derates: 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. Power loss is 14.6 W maximum, so account for that heat in the enclosure thermal budget. ## Approvals and compliance documentation As a Siemens SENTRON series MCCB, this breaker carries UL, CSA, and IEC certifications for global panel acceptance. RoHS and REACH compliance documentation is available from the manufacturer. The TM210 release provides thermal-magnetic protection with fixed settings — no ground-fault monitoring version is included on this variant.","metaTitle":"3VA1050-2ED42-0AC0 SENTRON MCCB, 50 A, 4-Pole, 52.5 kA at 24","metaDescription":"Siemens SENTRON 3VA1050-2ED42-0AC0 molded case circuit breaker, 50 A rated at 40 °C, 4-pole, 52.5 kA breaking at 240 V.
