Product FAQs
5 answersWhich panelboards are compatible with the NB111025 circuit breaker?
This breaker is designed specifically for installation in Federal Pacific NB and NBLP series panelboards.
What wire sizes and materials are accepted by the lugs on this breaker?
The terminal lugs accept wire gauges ranging from 14 AWG to 2 AWG and are rated for use with both aluminum and copper conductors.
What does the LI trip function indicate for the NB111025?
The LI designation means the breaker provides both long-time and instantaneous trip functions. This delivers standard thermal magnetic protection against sustained overloads and sudden short circuits.
Are there modern aftermarket replacements available for the Federal Pacific NB111025?
Yes. Because Federal Pacific is no longer manufacturing new breakers, aftermarket substitutes like the UBIF125NB are commonly used as direct drop-in replacements for this 25-amp model.
Is the Federal Pacific NB111025 considered a Stab-Lok breaker?
No. The NB series is a commercial bolt-on molded case circuit breaker. It does not use the plug-in Stab-Lok connection design found in residential Federal Pacific NA or NC series breakers.
