Schneider Electric C65108-400-40 Contactor Coil

Schneider Electric’s Square D C65108-400-40 Contactor Coil is a replacement magnet coil designed for compatible Square D contactors, allowing the control circuit to energize the coil and actuate the contactor without replacing the entire assembly. The coil is rated for 120 V AC at 60 Hz, a common specification for North American control systems, and is intended to energize when connected to standard control-voltage sources. As a dedicated coil, it powers the magnetic core that pulls the contactor’s moving contacts, enabling remote switching of power to motors, pumps, or other loads. The C65108-400-40 designation (also listed as 65108-400-40) identifies the exact coil style, so matching the part number is essential to ensure proper form fit, electrical characteristics, and reliable operation within your Square D or Schneider Electric control scheme. When sourcing this coil, verify compatibility with your specific Square D/SQD contactor family and coil voltage to avoid mismatches that could affect performance or safety.
