Square D 51019-243-56 DC Contactor Coil 120VDC

The Square D 51019-243-56 DC Contactor Coil is a replacement operating coil for Square D EC&M DC contactors, designed to energize on 115/120 VDC to activate the contactor’s power contacts. Sold as a coil-only option, 51019-243-56 is the dedicated part number used to replace worn or damaged coils in compatible Square D DC contactors. As a Square D (Schneider Electric) part, it is associated with the DC-control coil family and is listed in distributor catalogs and service literature such as Rexel’s operating coil listing for 51019-243-56. The coil is intended for use in DC-control circuits within industrial panels and is compatible with Square D’s EC&M line of DC contactors and other NEMA-style DC contactors. When nominal 120 VDC is applied to the coil, it energizes the magnetic circuit and moves the armature to switch the connected load, enabling control of motors and other electrical loads. The 51019-243-56 coil is widely referenced in replacement-part catalogs and cross-reference guides, confirming its status as the standard DC control coil for compatible Square D contactors.
