Product FAQs
6 answersWhat electrical panels are compatible with the Federal Pacific NA45?
The NA45 is designed exclusively for use in Federal Pacific Stab-Lok load centers. It features a plug-on mounting style that fits directly into these classic enclosures without the need for retrofit adapters.
Is there a direct substitute available for the Federal Pacific NA45?
Yes, the Connecticut Electric UBIF0145N is an exact cross-reference substitute for the NA45. Both are 45-amp, single-pole breakers designed to fit Federal Pacific Stab-Lok panels.
What wire sizes are accepted by the NA45 circuit breaker?
The terminal lugs on the NA45 accept wire gauges ranging from 14 AWG to 2 AWG. Always verify the correct wire size and insulation rating for your specific 45-amp branch circuit based on current electrical codes.
What does the LI trip function code mean on the NA45?
The LI designation indicates that this thermal-magnetic breaker includes both Long-Time and Instantaneous trip functions. The long-time function protects against sustained overloads, while the instantaneous function trips immediately during a short circuit.
How much space does the NA45 require in a Stab-Lok panel?
The NA45 is a full-size, single-pole breaker that requires one inch of space on the busbar in a Federal Pacific Stab-Lok load center.
Can I use the NA45 in a bolt-on Federal Pacific panel?
No, the NA45 features a plug-on connection type specifically for Stab-Lok load centers. It is not compatible with panels that require bolt-on connections, such as Federal Pacific Type NB breakers.
