3RT1934-6A - Siemens Contact Kit

3RT1934-6A - Siemens Contact Kit

When the main contacts in your Siemens S2 contactor start to wear down, you don’t always need to replace the entire unit. The 3RT1934-6A replacement contact kit gives you a straightforward way to restore proper operation using components designed to match the original setup.

This kit is built for 3-pole contactors used in AC-3 applications up to 15 kW. Inside, you’ll find three movable contacts, six fixed contacts, and the mounting parts needed for installation. Everything lines up the way it should, helping you get consistent contact and reliable switching in existing equipment.

The version we offer is a professionally engineered aftermarket replacement, made in the U.S.A., and designed specifically to replace the original contact kit. It’s a practical option for keeping older Siemens SIRIUS contactors in service without changing out the entire assembly.
