Rated motor power hits 4.5 kW at 500 V (AC-3, 50 Hz) and 5.5 kW at 690 V, meaning it handles typical three-phase induction motors in that power band — think small pumps, fans, conveyors. Auxiliary contact ratings are given across the coil voltage range: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V DC. That last one matters if you're switching a DC control circuit — the DC rating drops fast with voltage, so size your pilot devices accordingly. The contactor accepts screw-type terminals on the main circuit, with solid/stranded wire sizes up to 2x (0.75–4 mm²) or 2x 10 mm² single. Strip length and ferrule size follow standard practice; the listed cross-sections cover most panel wiring up to the rated current.
Front face is IP20 (finger-safe), terminals are IP00 (touch-hazard when live), so it's intended for enclosed panels, not open washdown areas. Side-by-side mounting is allowed with zero gap, which saves rail space in dense layouts. Maximum operating altitude is 2000 m — fine for most plants, but derate above that.
That's the spec you hand to the panel builder for the short-circuit rating.
