Eaton Cutler-Hammer 99-3873-2 Coil

The Eaton Cutler-Hammer 99-3873-2 constitutes a replacement control coil intended for use exclusively with the Advantage W200 and W201 series electrical contactor frames. This specific unit operates on a 120-volt power supply and accommodates Size 3 and Size 4 configurations as defined by the WCOIL34F reference code included in the original equipment designations for the Advantage platform. Installing this component restores the electromechanical linkage required to energize contactors and manage the flow of electricity through connected circuits during automated control sequences. The physical dimensions and electrical characteristics align with the established specifications for retrofitting older W-series installations that have experienced winding degradation or insulation failure due to prolonged usage in industrial environments. Proper selection of this part ensures compatibility with the existing magnetic mechanisms and latches inherent to the Cutler-Hammer product catalog for this specific voltage class and service duty.
