A heavy-duty AC contactor for 50/60 Hz circuits, rated up to 660 V standard or 1140 V optional, with currents of 63 A, 100 A, 160 A, 250 A, 315 A, 400 A, 500 A, 630 A, 800 A and 1000 A. Silver alloy contacts and an arc-resistant arc chute support a mechanical life near 10 million cycles, with coil voltages from 24 V to 380 V AC and standard 4NO + 2NC auxiliary contacts rated 16 A. Three-pole units handle three-phase motor starting and stopping, often paired with a thermal relay in industrial panels. Confirm the coil voltage, pole configuration and auxiliary contacts required.Key details:Materials: Silver alloy contacts; arc-resistant plastic arc chute
