Siemens 75D73251F Magnetic Coil

The Siemens 75D73251F Magnetic Coil is a replacement coil kit for Siemens/NEMA starting gear, sized for coil sizes 3 and 3.5 and identified by coil code F. It is a 120 VAC coil for 60 Hz operation (110 VAC for 50 Hz regions), making it compatible with Siemens coil requirements across different markets. This part number corresponds to a coil kit intended to energize the magnetic core of a contactor so the contacts close, and it is specifically used with Siemens DP series starters in the 120–150 A range, including the DP 42H family. Verified listings call it a “Coil Kit, 120VAC, SZ 3, 3.5,” with the 75D73251F designation, and reference both 60 Hz (120 V) and 50 Hz (110 V) variants. As a genuine replacement coil for 75D-series contactors, it is stocked by multiple distributors and used to restore or extend the life of Siemens/NEMA motor control equipment. In practical terms, it provides a direct swap-in coil for worn or failed magnets in compatible Siemens/NEMA starters, allowing motor circuits and associated equipment to be re-energized reliably without replacing the entire contactor.
