Three poles handle three-phase motor loads, and the adjustable trip class (selectable between 10A, 10/10E, 20/20E, and 30/30E) lets you match the thermal memory to the motor's starting profile — a 30E class gives a longer pickup time for high-inertia starts like conveyors or centrifuges. This breaker includes a communication function and phase failure detection, meaning it can report its status and trip on a lost phase before the motor burns out — a feature that matters in remote or unmanned installations.
Breaking capacity — the real number that decides selectivity
Rated breaking capacity is 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and drops to 3.7 kA at 690 V.
Mounting dimensions and panel fit
Maximum power loss is 4 W, so thermal management inside a sealed enclosure is straightforward; operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C.
