Schneider Electric 2936-S1-C33B Magnetic Coil

Schneider Electric's Square D 2936-S1-C33B magnetic coil is a replacement AC coil for Square D 2936-S1 size-1 magnetic contactors and starters, designed to fit the 2936 family’s size-1 coil form factor. The coil energizes the magnetic operator within the contactor assembly to actuate the contacts in control circuits, a common function in motor control and industrial automation panels. The C33B suffix identifies this specific coil variant within the 2936-S1 lineup. Online distributors and surplus outlets sometimes list the part as new surplus, reflecting its role as a genuine replacement coil for damaged or worn coils in 2936-S1 installations. Typical applications include control circuits in manufacturing lines, pumps, conveyors, and other industrial equipment that rely on Square D 2936 series contactors for reliable switching and control. When selecting a replacement coil, verify that the target device is a Square D 2936-S1 size-1 contactor and that the coil variant matches the original part to ensure proper fit and operation in your control scheme.
