What this 630 A MCCB is and what it does
The Siemens 3VA2463-6KP32-0AF0 is a SENTRON molded case circuit breaker (MCCB) rated for 630 A continuous current at 40 °C, with a three-pole design and a breaking capacity of 242 kA at 240 V AC. It's built for line protection — meaning it sits at the main feeder or large branch to guard against overcurrent and short-circuit faults, not for motor or generator protection. The communication function allows integration into a plant-wide monitoring system, so you can trip-status and load-profile from a PLC or SCADA without a separate shunt trip.
