The 52.5 kA breaking capacity at 240 V tells you it can safely interrupt a fault current up to that level without welding contacts or cascading upstream; at 415 V it still holds 32 kA, and at 690 V it's 7.5 kA. For a line protection design, that gives you selectivity headroom in most 400 V distribution panels. At 70 mm deep, 101.6 mm wide, and 130 mm tall, this breaker fits the standard SENTRON 4-pole MCCB footprint — it drops into the same DIN-rail or screw-mount panel cutout as the rest of the 3VA1 series. The 17.3 W maximum power loss means you should account for heat rise inside a sealed enclosure; derating from 63 A at 40 °C down to 58 A at 70 °C is already baked into the thermal curve, so no additional fudge factor needed if your ambient stays under 70 °C. ## Auxiliary switching and compliance Rated insulation voltage is 800 V, so it's comfortable in 480/277 V and 400/230 V systems with margin.","metaTitle":"Siemens 3VA1063-2ED42-0AF0 SENTRON MCCB, 63 A, 4-Pole, 52.5","metaDescription":"Siemens 3VA1063-2ED42-0AF0 SENTRON molded case circuit breaker, 63 A, 4-pole, breaking capacity 52.5 kA at 240 V.
