The NB2P125 is a bolt-on breaker designed for Federal Pioneer NB-series panelboards. It is not compatible with Stab-Lok (push-in) panels or other Federal Pioneer series such as NA. If you're unsure which series your panel is, send us the panel model number and our team can confirm compatibility.
Federal Pioneer breakers like the NB series are considered obsolete or hard-to-find, as Federal Pioneer is no longer in active production. Northern Breaker Group specializes in sourcing exactly these types of discontinued breakers — contact us for current stock availability on the NB2P125.
A 10kA interrupting capacity (AIC) is typically suitable for most residential and light commercial installations in Canada, where available fault current at the panel is generally well below 10kA. However, for commercial applications or locations close to a utility transformer, you should verify the available fault current with your electrician or utility to ensure the breaker's rating is adequate.
