Three poles handle three-phase circuits up to 690 V. Breaking capacity reaches 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V — the 240 V figure is the headline for high-fault industrial services; the 690 V rating is the tail, but still covers most motor-circuit fault levels.
Built-in auxiliaries and communication
Communication function is built in — the breaker can report status and accept commands over a bus, though the exact protocol depends on the communication module fitted. Max power loss is 13.5 W, which matters for thermal coordination inside a sealed panel — that's the heat the breaker dumps into the enclosure at full load.
