How it works

Finding replacement switches and switch parts for industrial air and vacuum circuit breakers requires a lot of information. From manufacturer to fuse size, each element can impact which switches and parts are viable replacements for your breakers.

We’ve broken out all the different categories that you should try and identify when looking for replacement switches and switch parts. Once you have enough information, you can go to a circuit breaker part supplier to find an exact replacement or an alternative solution. The more information you have available, the easier your search may be for your parts.
