Schneider Electric L2959 S49 W31A 120VAC Contactor Coil

Schneider Electric's Square D L2959-S49-W31A is a 120 VAC replacement magnet coil designed for use with Square D 2959-series contactor and timer devices. As part of the 2959-S49 family, this coil provides the magnetic force needed to energize the contactor's armature, enabling safe switching of loads in control circuits such as motors, lighting, and HVAC equipment. The W31A suffix denotes a specific variant optimized for 120-volt, 60 Hz operation; when replacing, ensure the host device specifies the same suffix and coil class to maintain compatibility and electrical performance. This coil is intended as a direct replacement for compatible Square D equipment, allowing technicians to restore coil function without replacing the entire contactor assembly, which minimizes downtime in panels and control cabinets. Typical applications include control circuits in industrial automation, building management systems, and equipment racks where 120 VAC coil control is standard. For best results, match the coil suffix (W31A) and voltage rating to your device's label, and consult the device's wiring diagram to confirm correct polarity and connector fit before installation.
