The S2 frame size (55 mm wide, 112 mm height, 115 mm depth) fits standard panel layouts; side-by-side mounting is permitted without derating for thermal stacking within the rated operating range of -25 to +60 °C.
Motor Duty & Ratings
Rated for AC-3 motor switching at 18.5 kW at 500 V (50/60 Hz), with a maximum electrical endurance of 1 000 operations per hour under AC-3 duty. For heavier AC-4 inching or plugging, the rate drops to 250 operations per hour — plan the application cycle accordingly. Coil draw at 24 V rated value is 10 A, and the contactor handles a pollution degree of 3 (conductive pollution typical in industrial enclosures).
Termination & Wiring
Screw-type terminals accept solid conductors up to 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²), and stranded up to 2x (0.75... 25 mm²). The wide clamping range covers standard control and power wiring without needing adapter lugs.
