3RT1944-6A - Siemens Contact Kit Description
Siemens 3RT1944-6A Replacement Contact Kit – 3-Pole, S3 Frame, Main Contacts (3 NO)
If your contactor is still in good shape but the contacts are worn, replacing the contact kit is often the smartest move. The 3RT1944-6A replacement contact kit is made to match Siemens S3 frame contactors, giving you the correct fit and function without needing to swap out the entire unit.
This kit includes 3 movable and 6 fixed main contacts, along with the mounting hardware needed to install them properly. It’s designed for 3-pole contactors used in AC-3 applications up to 30 kW, so it fits right into many existing motor control setups.
The version offered here is a professionally engineered aftermarket replacement, made in the U.S.A. It’s built to match the original contact configuration, making it a practical option for maintaining older equipment and keeping systems running as intended.
