It switches motor loads up to 22 kW at 500 V in AC-3 duty, or 11.4 kW at 690 V. For AC-4 (inching/plugging) the rating is 35 A at 400 V. AC-3 is the standard motor-switching category — the 22 kW figure at 500 V tells you the contactor handles full-load motor starts without welding the contacts. The 690 V rating (11.4 kW) covers higher-voltage European or Canadian industrial supplies.
Dimensions are 85 mm wide, 112 mm high, 115 mm deep — the Size S2 footprint is the standard for this current class.
Screw-type terminals accept 2 x (0.25 to 2.5 mm²) solid or 2 x (0.75 to 25 mm²) stranded. The 25 mm² upper end on stranded means it can take a heavy feeder cable without needing a lug adapter — useful for the main power path.
Operating conditions and ratings
Coil operates on 50/60 Hz. Maximum switching rates vary by duty: 1200 cycles/hour AC-1, 600 AC-2, 1000 AC-3, 300 AC-4.
