Four poles handle three-phase plus neutral, or you can land it as a 3-pole with a switched neutral.
The interrupting ratings step down with voltage as expected: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. At 415 V, the 121 kA figure covers most industrial services in North America and Europe without a second thought.
Ground-fault monitoring and communication — panel integration notes
This variant includes ground-fault monitoring via summation current formation on L + N conductors — it measures the vector sum of phase and neutral currents to detect leakage to earth. No separate GF relay needed if the trip unit supports it. Communication function is present, so it can talk to a higher-level system for power monitoring or remote tripping; check the trip unit variant for protocol support (PROFIBUS, PROFINET, Modbus). Power loss is 0.84 W maximum, negligible for enclosure thermal calculations.
