Breaking capacity is the headline spec here: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V — so it handles high-fault utility feeds or transformer secondaries where downstream gear needs a hard current-limiting upstream device. Thermal derating is published per degree: 630 A at 40 °C, dropping to 450 A at 70 °C. That curve matters for enclosure sizing — if your panel ambient runs 55 °C, the breaker carries 540 A continuous, not the 630 A label. Auxiliary switch complement is two HQ-form contacts; the shunt trip (STL) is factory-fitted for remote tripping. Communication function is onboard — this variant supports integration into a monitored distribution system. Physical footprint: 248 mm high, 138 mm wide, 110 mm deep — standard SENTRON 3VA frame size for a 630 A pole set. Mounts on a backplate or DIN rail via the accessory adapter; panel cutout planning should account for the 110 mm depth plus wiring clearance. ## Lifecycle status and sourcing posture The basic switch variant is listed as 3VA2463-6JQ32-0AA0; the -0JC0 suffix adds the shunt trip and auxiliary switch package.","metaTitle":"Siemens 3VA2463-6JQ32-0JC0 SENTRON MCCB, 630 A, 3-Pole, 242","metaDescription":"Siemens SENTRON 3VA2463-6JQ32-0JC0 molded case circuit breaker, 630 A full-scale, 3-pole, line protection.
