The Siemens SENTRON 3VA2463-7HL32-0BL0 is a 3-pole molded case circuit breaker rated for 630 A continuous at 40 °C, with a breaking capacity of 330 kA at 240 V and 242 kA at 415 V. It's designed for line protection and comes fitted with an undervoltage release plus a full set of auxiliary switches — two aux, one trip alarm, one electrical alarm. This is a panel-mounted unit, 248 mm tall by 138 mm wide by 110 mm deep, so it'll fit a standard MCCB slot in most distribution boards.
The 630 A continuous rating at 40 °C is the headline number, but if your panel runs hotter — and most do inside an enclosure — you need the derating curve: at 50 °C it's 593 A, at 60 °C it's 557 A, at 70 °C it's 520 A. That's high-end fault current handling — typical for large transformer secondaries or industrial mains. The trip indicator and undervoltage release are already built in. The auxiliary switch configuration — two aux switches plus a trip alarm and an electrical alarm — gives you remote status for both normal position and fault events without adding separate modules.
