Interrupting capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. This is a straight line-protection breaker for a panel that needs a fixed-trip 50 A feed. The 50 A rating holds flat from 40 °C to 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. Ambient inside the enclosure matters — if the panel runs hot, you lose 5 A by 70 °C. Dimensions are 130 mm tall, 101.6 mm wide, 70 mm deep. No N-conductor protection on this variant.","metaTitle":"Siemens 3VA1050-3ED42-0AD0 SENTRON MCCB, 50A, 4-Pole, TM210","metaDescription":"Siemens 3VA1050-3ED42-0AD0 SENTRON 4-pole molded case circuit breaker, 50 A continuous, TM210 thermal-magnetic trip, 75.6 kA at 240 V.
