Motor ratings that decide the fit
Rated 3 kW at 400 V AC-3 — the standard motor-switching duty for a size S00 contactor. At 480 V the current rating is 4.8 A; at 600 V it's 6.1 A. The AC-4 rating at 400 V is also 3 kW, which means this assembly handles reversing under load without derating for inching or plugging duty. Horsepower ratings span 1.5 hp at 200/208 V up to 5 hp at 575/600 V, covering common North American motor frames in this current class.
Coil and control circuit
Magnet coil rated 110 V at 50 Hz and 120 V at 60 Hz. Coil connections use spring-type terminals.
Environmental limits and shock
Shock resistance rated at 10.5 g for 5 ms and 6.6 g for 10 ms on both AC and DC axes.
