Breaking capacity runs 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. At 690 V the 9 kA rating still clears a fault on a 690 V drive line, but you'd verify coordination with the upstream transformer impedance. Thermal derating is published per degree: 630 A at 40 °C, 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, 450 A at 70 °C. Maximum power loss is 164.5 W, which matters for enclosure heat rise calculations. ## Dimensions, mounting, and auxiliary options The 110 mm depth (4.33 in) leaves room behind the panel door for wiring gutters and auxiliary modules. Communication function is present, meaning it can integrate with a higher-level monitoring system via optional communication modules.","metaTitle":"Siemens 3VA2463-5JQ32-0CA0 SENTRON MCCB, 630 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2463-5JQ32-0CA0 molded case circuit breaker, 630 A at 40 °C, 3-pole, adjustable 945–5670 A trip, 187 kA at 240 V.
