546A780G51 - GE Contact Kit

If you’ve got a contactor that’s still mechanically sound but the contacts are worn, this is usually the fix. The 546A780G51 contact kit is made for those situations where you just need to replace the working parts and move on—no need to swap out the entire unit.

This is a 3-pole, Size 2 contact kit built to fit CR205, CR206, CR305, and CR306 contactors. It lines up the way you’d expect, so if you’ve worked on these before, there’s nothing unusual about the install. It’s a direct replacement, plain and simple.

The goal here isn’t to change anything about your setup—it’s to keep it running the way it was designed to. Once installed, you’re restoring proper contact engagement and keeping your equipment in service without overthinking it.
