It measures 45 mm wide by 57.5 mm tall by 72 mm deep, so it tucks into tight DIN-rail enclosures without hogging space. The screw terminals accept solid or stranded wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²) per clamp.
For motor switching, the AC-2 rating at 400 V is 3 kW, and the AC-4 rating at 400 V is 6.5 A — that's the figure that matters for reversing or inching duty, where the contactor makes and breaks stalled-rotor current. At 690 V it handles 4 kW, and at 500 V it handles 3.5 kW. The coil operates on 50/60 Hz at 0.8 to 1.1 times rated voltage (50 Hz) or 0.85 to 1.1 (60 Hz).
Where you'll use it — panel and environment
Side-by-side mounting is allowed without derating, so you can gang several contactors in a row. The front and terminals are rated IP20 — finger-safe for a panel, but not for washdown. Maximum installation altitude is 2000 m. Mechanical life is typical 30 million operations.
