It is rated for 2.5 A line current and carries a 100 kA breaking capacity at 400 V AC (IEC 60947-2), meaning it can safely interrupt fault currents up to that level without cascading damage upstream in the panel. The 24 V AC coil is standard for this variant. Motor power ratings span 0.75 kW at 400/415 V up to 1.5 kW at 690 V, covering a range of small induction motor loads — pumps, fans, conveyors — in control panels. The magnetic trip is set at 33.5 A, providing short-circuit protection coordinated with the thermal overload curve.
At 45 mm wide (1.8 in), it occupies a single modular space on the rail — useful when packing multiple starters into a compact enclosure. IP20 finger-safe terminals are standard for panel-side wiring. Screw-clamp terminals accept 1 to 6 mm² solid or stranded wire; torque to 1.7 N·m. The rotary knob control type allows manual on/off and reset without tools.
Flame retardance is V1 per UL 94; glow-wire tested to 850 °C (IEC 60695-2-1). Climatic withstand per IACS with TH protective treatment for tropical/humid storage. Electrical durability is 100,000 cycles under AC-3 duty at 440 V — the rating that governs real motor-switching life.
