The ABB A260W-20-11-84 is a 2-pole welding contactor from the A260 series, designated for high-duty-cycle welding applications. Its lifecycle stage is listed as eol_hot, meaning the manufacturer has formally ended production and the part is in its final phase of availability through the supply chain.
This is a 2-pole contactor built for the thermal and mechanical demands of resistance welding — high inrush currents, repetitive cycling, and sustained weld-time intervals. It mounts in the standard contactor footprint; verify the coil voltage and auxiliary contact configuration against your existing panel layout before ordering the replacement.
