The interrupting ratings climb steeply with voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. That SCCR headroom means it clears high-fault conditions without cascading upstream — critical for a selective coordination study.
The 3-pole form factor with integrated shunt trip and aux switches means no additional wiring compartments needed for those functions; the auxiliary switch design is HQ (high-qualified), typically rated for signal-level switching into a PLC input. Verify the rotary handle or extended-rotary mechanism if the breaker sits behind a door — the base unit ships without an operating mechanism cover.
