Replacement Contact Kit
The SIEMENS 75HF14 kit supplies a single set of replacement contacts for compatible Siemens contactors. It includes movable contacts, stationary contacts and the necessary springs to restore reliable switching performance. Maintenance teams use it to refresh worn contact surfaces without replacing the entire contactor assembly.
When to Install the Kit
This kit replaces contacts that have pitted, welded or eroded after extended service in NEMA Size 3 starters. The upgrade is worth it when the contactor frame and coil remain sound but the contact tips no longer make clean, low-resistance closure. It avoids the cost and downtime of swapping a complete starter unit.
Series Compatibility Limits
The kit is built for the Siemens Multiple Class contactor series in NEMA Size 3 only. It will not fit other NEMA sizes, different Siemens series or contactors from other manufacturers. Verify the exact series and size marking on the existing device before ordering to ensure correct fit and electrical rating.

Questions about this item
Which Siemens contactors accept the 75HF14 kit?
The kit fits Siemens Multiple Class Contactors in NEMA Size 3.
How is the single contact assembly installed, and what step is often missed?
Remove the old movable and stationary contacts with their springs, then seat the new parts in the same order; the step often missed is reinstalling the springs so the movable contact returns cleanly.
What parts will need replacement after extended service?
The movable contacts, stationary contacts and their return springs all wear together and are replaced as a set with another 75HF14 kit.
