Motor power coverage: 11 kW at 400/415 V, 15 kW at 500 V, 18.5 kW at 690 V. That's the real-world selection number — match the motor nameplate kW to the voltage present on your line. Breaking capacity varies with voltage: 100 kA at 230/240 V and 400/415 V, then 50 kA at 440 V, 12 kA at 500 V, 6 kA at 690 V. If your plant runs at 690 V, the 6 kA Icu still covers most downstream faults, but verify against your transformer's prospective short-circuit current. The 55 mm width and 136 mm depth fit standard enclosure backplates — no special spreaders needed (connection pitch is 17.5 mm). Rated for uninterrupted duty per IEC 60947-4-1, so it's fine for continuous motor runs.
Compliant with EN/IEC 60947-2 (circuit-breaker standard) and EN/IEC 60947-4-1 (motor-starter standard), plus UL 60947-4-1 and CSA C22.2 No 60947-4-1. Also listed for IEC/EN 60335-1 and -2-40 (appliance safety) — useful if the breaker lands in a packaged HVAC or refrigeration skid. Phase-failure sensitivity is built in per IEC 60947-4-1, so it protects against single-phasing on a three-phase motor.
