It's sized for motor protection duties: 3 kW at 400/415 V AC, up to 7.5 kW at 690 V AC. Phase failure sensitivity is built in per IEC 60947-4-1, so it will trip if one phase drops out on a three-phase motor — preventing single-phasing damage. The magnetic trip threshold is set at 149 A, which is about 15x the rated current, giving good inrush headroom for standard induction motors.
Dimensions are 89 mm high, 54 mm wide, 78.5 mm deep — fits a standard 4-module wide DIN-rail footprint. Screw-clamp terminals accept up to 2 x 6 mm² solid or 2 x 4 mm² flexible with ferrule; tighten to 1.7 N·m. The auxiliary contact block is integrated as 1 NO + 1 NC side-mounted, so you get status feedback without an add-on module.
Fire resistance is tested to 960 °C per IEC 60695-2-11. Climatic withstand conforms to IACS (marine environment corrosion resistance). Operating altitude is limited to 2000 m without derating.
