Rated for motor duty at 5.5 kW on a 400 V three-phase supply, it also covers 7.5 kW at 500 V and up to 11 kW at 690 V. The magnetic trip threshold sits at 253.4 A, and it includes phase-failure sensitivity per IEC 60947-4-1 — so a lost phase on the line side won't leave the motor single-phasing to destruction.
For most industrial installations fed from a 500 kVA or smaller transformer, that's more than enough headroom to avoid a cascading failure. The 6 kA rating at 690 V is a reminder that high-voltage faults are harder to interrupt; if your panel runs at 690 V, coordinate upstream accordingly. The 1 NO + 1 NC auxiliary contact set on the front lets you wire a status feedback to the PLC or a remote indicator without an add-on block. Electrical durability is rated at 100,000 cycles under AC-3 duty at 415 V, which is typical for a motor-starting profile — expect the mechanical life of 100,000 cycles to be the limiting factor if you're cycling it as a disconnect.
The 45 mm width (3-module footprint) fits standard enclosure cutouts. Power terminals accept up to 6 mm² solid or 4 mm² flexible with ferrule — two conductors per terminal, which helps when daisy-chaining to a downstream contactor. Tightening torque is 1.7 N·m on the screw clamp terminals. IP20 finger-safe protection on the front, with an IK04 impact rating — adequate for enclosed panels where operators access the handle.
Certified to 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 for North American installations. Also listed for IEC/EN 60335-2-40 (heat pump and air conditioner) and IEC/EN 60335-1 Clause 30.2 (glow-wire test at 960 °C per IEC 60695-2-11). Climatic withstand per IACS covers marine and humid environments.
