How it works

Finding replacement circuit breakers requires a lot of information. We’ve broken out all the different categories that you may need to find a proper replacement breaker for your needs. The more information you can provide, the easier it will be for a circuit breaker supplier to identify a used or remanufactured replacement option.

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 a replacement circuit breaker in stock.
