It carries a 121 kA breaking capacity at 240 V, stepping down to 75.6 kA at 415 V and 52.5 kA at 440 V — enough headroom for most industrial distribution panels where fault current runs high on the secondary side of a large transformer. The line protection version means it's configured for feeder and main breaker duty, not motor branch circuit protection. The 63 A rating holds flat from 40 °C up to 50 °C, then derates to 60.48 A at 55 °C and 56.7 A at 70 °C — so if the breaker sits in a hot enclosure near other heat sources, you lose about 10 % of capacity at the top end. The 121 kA interrupting rating at 240 V is the headline figure; at 415 V it's still 75.6 kA, and at 690 V it drops to 11.9 kA. You set the breaker once at 63 A and it stays there. The integrated shunt trip (STL) lets you trip the breaker remotely from an emergency stop or a PLC digital output; the auxiliary contact version includes 2 HQ switches for status feedback to the control system. The breaker measures 101.6 mm wide by 130 mm tall by 70 mm deep — a standard 4-pole MCCB footprint for DIN-rail or panel-mount installation.","metaTitle":"Siemens SENTRON 3VA1063-4ED42-0HC0 MCCB, 63 A, 121 kA","metaDescription":"Siemens SENTRON 3VA1063-4ED42-0HC0 molded case circuit breaker, 63 A rated current, 121 kA breaking at 240 V, 4-pole, line protection with TM210 release and shunt trip.
