3RT1946-6A - Siemens Contact Kit Description
3RT1946-6A - Siemens Contact Kit
When contacts inside a contactor start to wear down, you don’t always need to replace the entire unit. The 3RT1946-6A replacement contact kit gives you a straightforward way to bring your Siemens S3 contactor back into working condition using components designed to match the original setup.
This kit includes everything needed to replace the main contacts—three movable and six fixed contacts—along with the required mounting parts. It’s built for 3-pole, normally open configurations and supports AC-3 applications up to 45 kW, making it a practical fit for many motor control systems already in service. If you're maintaining existing equipment and want to keep things running without changing your setup, this is the kind of part that does exactly what it’s supposed to—no guesswork, no modifications.
Manufactured in the U.S.A. as a professionally engineered aftermarket replacement, this contact kit is made to align with the original form and fit, so installation is familiar and predictable. These are the kinds of components that hold up over time and help extend the life of your equipment.
