The 630 A rating is the continuous current at 40 °C ambient; as the temperature climbs, the breaker derates in a published curve — at 50 °C it's good for 570 A, at 70 °C it's 450 A — so if your panel runs hot, you size off the derated number, not the 40 °C sticker. The 3VA2463-5JQ42-0AA0 delivers 187 kA at 240 V, 121 kA at both 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. The sharp drop at 690 V tells you this breaker is really optimized for 240–500 V distribution — at 690 V you're near its ceiling, so if your system runs at that voltage, verify the available fault current stays under 9 kA or step up to a higher-rated frame. The breaker measures 248 mm high, 184 mm wide, and 110 mm deep. Those are the dimensions you'll need for backpanel layout and enclosure depth clearance. The 110 mm depth means it fits most standard distribution enclosures without a deep-can extension, but check your gland-plate clearance if you're mounting it near the back wall of a shallow cabinet. The 184 mm width for a 4-pole frame is typical for this class — it'll occupy three full 54 mm DIN spaces plus a bit of overhang on the end. ## Environmental limits and power loss ## Communication and monitoring features This breaker includes a communication function and a ground-fault monitoring version that uses summation current formation on L + N conductors. It does not have an undervoltage release, a voltage trigger, or a trip indicator. The adjustable overload protection range spans from 126 A (minimum) to 630 A (full-scale), so you can dial in the trip point to match your downstream load without swapping thermal elements.","metaTitle":"Siemens 3VA2463-5JQ42-0AA0 SENTRON MCCB, 630 A, 187 kA","metaDescription":"Siemens SENTRON 3VA2463-5JQ42-0AA0 molded case circuit breaker, rated 630 A continuous at 40 °C with 187 kA breaking capacity at 240 V.
