The Siemens SENTRON 3VA2463-7HL32-0KJ0 is a 3-pole molded case circuit breaker (MCCB) rated for 630 A continuous current, designed for line protection in distribution panels and industrial switchgear. Its breaking capacity hits 330 kA at 240 V and 242 kA at 415 V, meaning it can safely interrupt very high fault currents without upstream damage — critical for high-available-fault installations like large motor control centers or transformer secondaries.
The continuous current is 630 A at 40 °C, derating to 520 A at 70 °C — so if your panel ambient runs hot, the effective ampacity drops. Maximum breaking capacity spans 5 670 A (the high end of the adjustable trip range) down to a minimum of 945 A, giving you selectivity headroom downstream.
Dimensions are 248 mm high, 138 mm wide, 110 mm deep — fits a typical 600 mm wide enclosure with room for cable entry below. The 3-pole block occupies three module positions; leave clearance above for the arc chute exhaust.
