The Siemens 3VA2463-6KP32-0AJ0 is a SENTRON molded case circuit breaker rated 630 A continuous current at 40 °C, with a breaking capacity of 242 kA at 240 V and 187 kA at 415 V. At 415 V the breaking capacity is 187 kA, dropping to 40 kA at 690 V. The 630 A frame also carries a full temperature derating curve: 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. That 110 mm depth matters for enclosure depth planning — it fits standard 200 mm deep MCC buckets but check your gland-plate clearance if the panel is shallow.
Integration — panel fit and wiring
Three-pole design with no undervoltage release and no ground-fault monitoring module. Communication function is present — typically via a communication module that plugs into the ETU's accessory slot, enabling remote trip indication and current monitoring. Power loss at full rated current is 162 W maximum — account for that heat in your enclosure's thermal budget. Latching endurance rated at 15,000 operations — that's mechanical life, not electrical. For frequent switching duty, the electrical life at rated current will be lower; this breaker is designed for protection, not as a switching contactor.
