Square D 9998PC334 Replacement Mechanism Assembly

Square D 9998PC334 Replacement Mechanism Assembly is a replacement switch mechanism for Square D Class 9998 motor starters, designed to service models 9035DR10, DW10, DR30, and DW30. This assembly replaces worn internal mechanism components to restore proper actuation and control without replacing the entire starter, making it a practical solution for refurbishing aging equipment. As part of Schneider Electric’s legacy 9998-class parts, 9998PC334 is listed in official catalogs and distributor listings as the Replacement Switch Mechanism for the specified models. Use during maintenance or field service to extend the life of existing 9998-series equipment and keep the control wiring and mounting compatible with the original design.
