Square D 31063409 Type S Replacement Contactor Coil, 310 Series

Square D 31063409 Type S Replacement Contactor Coil, 310 Series

The Square D Type S Replacement Contactor Coil, 310 Series, lets electricians and panel builders quickly swap the coil in a Type S contactor or starter to convert it to a different control circuit voltage or NEMA size application. This coil family is available in two configurations: 208VAC 60Hz for NEMA Size 3 starters, and 440/480VAC 50/60Hz for NEMA Size 2 starters, covering a broad range of Type S contactor and starter rebuild needs. Depending on the option selected, the coil is compatible with class 8903 type SQ lighting contactors, class 8502 type SE contactors, and class 8910 type DPA12/SYD138 contactors. Replacing the coil restores or reconfigures the unit for its intended control voltage without the added cost of sourcing a whole new contactor or starter.

Key Features
