Product FAQs

6 answers
Is the NA2P125 the same breaker as the 2P125FED?

Yes, 2P125FED is the alternate catalog number for the NA2P125. Both part numbers represent the exact same 125A, 2-pole Federal Pioneer Stab-Lok circuit breaker manufactured by Schneider Electric.

Which obsolete Federal Pioneer breakers can the NA2P125 replace?

This breaker serves as a direct, modern replacement for older NA2125 and UBIFPE125N circuit breakers used in vintage Stab-Lok panelboards.

Can I install the NA2P125 in a standard Square D or Homeline panel?

No. Despite being manufactured by Schneider Electric (the parent company of Square D), the NA2P125 features a specific plug-on design that is only compatible with Federal Pioneer Stab-Lok load centers and panelboards.

Does the NA2P125 require bolt-on connections to the busbar?

No, this is a plug-in style breaker. It snaps directly onto the Stab-Lok busbar without the need for bolted connections, though the load side wires must be secured to the lugs.

Does the NA2P125 meet current safety standards for Stab-Lok replacements?

Yes. As an authentic Federal Pioneer product manufactured by Schneider Electric, it carries CSA approval, ensuring it meets modern safety and performance standards for compatible Stab-Lok panels.

What does the LI trip function code mean on the NA2P125?

The LI designation indicates that the breaker uses a thermal-magnetic trip unit providing Long-Time (L) protection against sustained overloads and Instantaneous (I) protection against sudden short circuits.
