Lifecycle status — end-of-life procurement
The A110W-30-11-84: This is a welding-duty contactor, 3-pole, 140 A rating, designed for the high inrush and sustained current demands of resistance welding controls.
Type and application fit
Listed as an IEC Contactor, the A110W-30-11-84 is built to IEC 60947-4-1 standards for motor starting and switching, with a specific welding-duty variant that handles the high peak currents and rapid cycling typical of spot-welding transformers. The 140 A rating at Size W3 means it is intended for larger welding guns or multiple weld heads sharing a common contactor — not a general-purpose motor starter.
