The Siemens 3VA2463-5KP32-0CC0 is a SENTRON molded case circuit breaker rated for 630 A continuous current at 40 °C, with a breaking capacity of 187 kA at 240 V — that's the fault it can safely interrupt without welding contacts or venting arc gas into the enclosure. The auxiliary contacts report breaker position back to a PLC or status lamp without extra wiring. No trip indicator on the front, so if you need visual trip indication at the breaker, plan for an auxiliary contact wired to a panel light.
Derating and thermal reality
At 45 °C it's 600 A, at 50 °C it's 570 A, at 55 °C it's 540 A, at 60 °C it's 510 A, at 65 °C it's 480 A, and at 70 °C it's 450 A. If your panel ambient hits 50 °C — say it's near a furnace line or under a non-climate-controlled roof — the breaker derates to 570 A. Size your load accordingly or spec a higher frame. The 248 mm height, 138 mm width, 110 mm depth footprint fits standard SENTRON 3VA mounting plates; measure your existing cutout before ordering.
