The 480 V AC control coil means the pickup and dropout voltage must match the control transformer or PLC output driving it — a 120 V or 24 V coil version is a different order code. ## Surface mount — panel integration Surface-mount, not DIN-rail snap-on — the contactor bolts to a backplate or sub-panel. Plan for screw-termination clearance and wire-bend radius around the 1 NO auxiliary contact block.","metaTitle":"ABB A9-30-10-51 Contactor, 21 A, 600 V AC, 3-Pole","metaDescription":"ABB A9-30-10-51 3-pole contactor, 21 A, 600 V AC, 480 V AC coil, 1 NO auxiliary.
