It carries a 440 kA interrupting capacity at 240 V, stepping down to 330 kA at 415 V and 220 kA at 500 V — numbers that tell you this breaker handles high-fault industrial service without cascading upstream. The communication function onboard means it can talk to a PLC or BMS for remote trip indication or load shedding, which saves a panel builder an aux contact block and a separate I/O point.
That is unusual for a compact MCCB and simplifies panel thermal calculations. Interrupting ratings are given at multiple voltages: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V.
