Rated for 22 kW at 400 V in AC-2 duty (slip-ring motor starting) and 41 A at 400 V in AC-4 duty (plugging/reversing/inching), this contactor handles the heavy switching cycles that wear out smaller frames. The AC-3 maximum switching rate is 800 cycles per hour, while AC-4 allows 300 cycles per hour — the AC-4 figure is the one that governs reversing or jogging applications. Operating temperature range is -25 to +60 °C, storage from -55 to +80 °C, with degree of pollution 3 (conductive pollution typical in industrial enclosures).
Solid wire accepted: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). Stranded: 2x (0.75 to 25 mm²). Minimum permissible cross-section at 40 °C is 16 mm² for the main circuit — that's the thermal limit for full-rated current without derating. Dimensions: 55 mm wide, 112 mm high, 164 mm deep.
The contactor is rated for 50 Hz supply (rated value 50 Hz, operating range 0.8 to 1.1 times nominal frequency). Coil operating times: AC closing 7 to 20 ms, arcing time 10 to 15 ms.
