How it works

Finding replacement parts for industrial air and vacuum circuit breakers requires a lot of information. From manufacturer to case options, there are several elements that can impact which protective relays are viable replacements for your breakers.

We’ve broken out all the different categories that can help you identify proper replacement relays or alternative solutions. The more information you can collect, the easier your search will be for these parts. Once you have enough information, you can go to a circuit breaker part supplier to find an exact replacement or an alternative solution.

Use the categories below to gather the information you need. Once you have enough information, use NPE on the Go to have our team see if we have the right replacement relays in stock.
