It carries a rated insulation voltage of 800 V and delivers a breaking capacity of 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V — figures that define its fault-interruption capability across common industrial voltage levels. ## Breaking Capacity — What It Means for Coordination At 415 V, the 52.5 kA breaking capacity sits well above typical utility fault levels for most industrial services (often 25–50 kA). That headroom simplifies selective coordination downstream — the MCCB can clear a fault without upstream devices needing to trip, which keeps the rest of the panel live during a branch fault. The part is still usable in those circuits, but coordination studies need to account for the reduced interrupting capability at higher voltage. ## Current Derating and Ambient Temperature Above that, the continuous current must be derated: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. ## Undervoltage Release and Auxiliary Options It ships without auxiliary contacts or a shunt trip, and without a voltage trigger or communication module. The integrated auxiliary trip is order code 3VA9608-0BB24, which can be sourced separately if field retrofitting is needed. No ground-fault monitoring or phase-failure detection is built in. The 101.6 mm width (4-inch nominal) matches the standard footprint for a 4-pole MCCB in a distribution panel, so it drops into existing SENTRON or comparable DIN-rail or panel-mount cutouts without enclosure modification.","metaTitle":"Siemens 3VA1063-3ED42-0CA0 SENTRON MCCB, 63 A, 4-Pole, TM210","metaDescription":"Siemens 3VA1063-3ED42-0CA0 SENTRON molded case circuit breaker, 63 A rated at 40 °C, 4-pole, TM210 release, breaking capacity 75.6 kA at 240 V.
