The 4-pole construction handles three-phase plus neutral, common for North American and European distribution panels where a switched neutral is required. Communication function and other measurement functions are built in, meaning this breaker can report status and load data back to a BMS or PLC without an add-on module.
Short-circuit ratings that matter for panel coordination
Short-circuit breaking capacity is 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. That 440 kA figure at 240 V covers high-fault utility feeds common in industrial services; the 52.5 kA at 690 V still clears most motor-circuit faults without upstream fuses.
