Rated motor power is 18.5 kW at 500 V and 10 kW at 690 V — that's the AC-3 switching capacity for a standard squirrel-cage induction motor. AC-3 duty allows 1 000 ops/h, while the punishing AC-4 plugging/reversing duty is limited to 250 ops/h. Auxiliary contact ratings cover the common control voltages: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V. The coil operating range spans 0.8 to 1.1 x rated voltage at 50 Hz, and 0.85 to 1.1 at 60 Hz — so a saggy 24 VDC control bus that drops to 19 V still holds the contactor in. Arcing time runs 10 to 15 ms; DC dropout is 20 to 30 ms.
Dimensions: 129 mm high, 55 mm wide, 164 mm deep. Wire range on the main circuit accepts 2x (0.75 to 25 mm²) stranded or 2x (0.25 to 2.5 mm²) solid; auxiliary terminals take 2x (0.75 to 16 mm²) stranded or 2x (0.25 to 2.5 mm²) solid. Strip length and ferrule sizing follow the standard screw-terminal practice for this S2 frame. The contactor survives 15 g / 5 ms shock on AC, 8 g / 10 ms on DC — adequate for most industrial panel installations that aren't mounted directly on a vibrating press.
