How it works

Finding replacement parts for use and remanufactured circuit breakers is difficult without the right information. Our guide gives you all the different details that you should try to identify when it’s time to replace your switchgears or switchgear parts.

We’ve broken down all the different categories that are important for industrial air and vacuum circuit breakers. Once you collect as much of that information as you can, you can take those details to a circuit breaker part supplier so that they can help you 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 whole switches and switch parts in stock.
