The 330 kA interrupting capacity at 240 V means it can clear a bolted fault at the main service entrance without upstream coordination issues — that rating holds through 242 kA at 415/440 V and 187 kA at 500 V, so it handles the high-fault conditions common in industrial switchgear. At 690 V the breaking capacity drops to 4.5 kA, which still covers most motor-circuit faults at that voltage class. The thermal-magnetic trip curve is derated by ambient temperature: the breaker carries its full 250 A up to 50 °C, then steps down to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C.
The 3-pole form factor bolts directly onto the mounting plate; no DIN-rail adapter needed for this frame size. That covers remote status indication and shunt-trip capability without adding external relay logic. Communication function is onboard — the basic switch variant is 3VA2225-7KP32-0AA0, and this BL0 suffix adds the communication module for integration with a BMS or PLC.
