Those numbers govern selectivity coordination downstream — at 415 V common in industrial panels, 75.6 kA gives headroom for most transformer-fed fault currents without cascading upstream. ## Thermal derating — what the 100 A rating actually means Above that, it steps down: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. The 4-pole width (101.6 mm) is standard for this frame size — it occupies four 25.4 mm module spaces on a DIN rail, matching the SENTRON 3VA family footprint.","metaTitle":"Siemens 3VA1010-4ED42-0KA0 SENTRON MCCB, 100 A, 4-Pole, 121","metaDescription":"Siemens SENTRON 3VA1010-4ED42-0KA0 molded case circuit breaker, 100 A, 4-pole, TM210 release, shunt trip.
