Schneider Electric 31063-409-38 N 120V Circuit Breaker

Schneider Electric's Square D 31063-409-38-N is a 120 V AC magnetic coil for current-style Square D contactors used in motor-control circuits. This 60 Hz coil energizes the contactor to close its main contacts, enabling controlled switching of connected loads within electrical panels or machine-control assemblies. Identified by part number 31063-409-38, the coil provides a 120 V control input designed for use with compatible Square D contactors in the motor-control family. Typical applications involve starting and stopping motors in industrial equipment where a low-voltage control signal is used to energize the line-voltage circuit. For reliable operation, match the coil to your contactor’s size and pole configuration and verify compatibility with your exact device, noting that broader Square D catalogs include 120/240 V variants for certain pole counts.
