The Siemens 3VA2463-5KP32-0HH0 is a SENTRON molded case circuit breaker (MCCB) for line protection, rated 630 A continuous at 40 °C and 187 kA interrupting at 240 V — that SCCR handles high-fault utility feeds without cascading upstream. At 415 V it still breaks 121 kA, so it fits main breaker positions in 400 V distribution panels where fault current runs high. The 110 mm depth and 138 mm width keep it within a standard MCCB footprint for retrofit into existing SENTRON or third-party cubicles.
Derating and thermal budget
Maximum power loss is 162 W, which adds to the enclosure's heat load; factor that into the ventilation or cooling calculation.
Communication function is built in, so it can report status to a higher-level controller or BMS. No undervoltage release or phase failure detection on this variant.
