Product FAQs

5 answers
What is the difference between Federal Pacific NA and NC series circuit breakers?

The NA series breakers are the standard thick style, measuring 1 inch wide per pole. The NC series breakers are the thin or half-size style, measuring 1/2 inch wide per pole. The NA25 is a 1-inch wide, single-pole breaker.

Are there known safety concerns with Federal Pacific Stab-Lok panels and breakers?

Yes. Original Federal Pacific Electric (FPE) Stab-Lok panels and breakers have a well-documented history of failing to trip during overcurrent or short-circuit conditions. Many licensed electricians and inspectors strongly recommend replacing the entire FPE panel to ensure facility safety.

Are there modern aftermarket replacements available for the Federal Pacific NA25?

Yes. Connecticut Electric manufactures modern, ETL-listed aftermarket replacement breakers under the UBIF series. These are specifically designed to fit FPE Stab-Lok load centers and provide a safer alternative when a complete panel replacement is not immediately possible.

Can I install the NA25 in a modern load center?

No. The NA25 features a proprietary Stab-Lok plug-on connection that is exclusively compatible with older Federal Pacific Electric load centers. It will not fit in modern panels from brands like Square D, Eaton, or Siemens.

How does the NA25 connect to the panel busbar?

The NA25 utilizes a proprietary Stab-Lok plug-on design. The breaker stabs directly onto the panel busbar, securing the electrical connection without the need for mounting bolts or external fasteners.
