477B477G05 - Eaton Contact Kit

If you’re maintaining older Eaton contactors, you know the drill—when the contacts wear down, performance starts to slip. The Eaton 477B477G05 contact kit is made to handle exactly that. It’s a straightforward replacement designed for GPA530 and GCA530 contactors (Size 5, single-pole, 1963 and newer).

Instead of replacing the entire unit, this kit lets you swap out the worn contact components and keep your existing equipment in service. It matches the original setup, so you’re not guessing about fit or compatibility. It also replaces older part numbers 441A241H06 and 655C272G01, which is helpful when you’re working with legacy systems and older documentation.

This is the kind of part that’s typically used during routine maintenance or when something just isn’t making proper contact anymore. Once installed, it helps bring the contactor back to normal operation—nothing fancy, just doing what it’s supposed to do.
