Product FAQs
7 answersWhich panelboards are compatible with the Federal Pacific NB111035?
This breaker is designed exclusively for use in legacy Federal Pacific NB series panelboards. It will not fit in FPE Stab-Lok load centers.
Can I use this breaker in a standard FPE Stab-Lok residential panel?
No. The NB111035 is a bolt-on circuit breaker designed for commercial NB panelboards. It is not compatible with plug-on Stab-Lok load centers that require NA or NC series breakers.
How does the NB111035 connect to the panelboard busbar?
It features a bolt-on mounting style, meaning it fastens directly to the panel busbar with screws for a secure, vibration-resistant connection.
What size and type of wire can be used with the NB111035?
The load-side lugs on this breaker accept 14 AWG to 2 AWG wire and are rated for both aluminum and copper conductors.
What type of trip mechanism does the NB111035 use?
It utilizes a fixed thermal-magnetic trip unit, providing both long-time thermal protection against overloads and instantaneous magnetic protection against short circuits.
Is this breaker suitable for 240V applications?
No. The NB111035 is a single-pole breaker rated for 120VAC maximum and cannot be used for 240V multi-pole applications.
Are there aftermarket replacements available for the Federal Pacific NB111035?
Yes. Because original Federal Pacific breakers are obsolete, aftermarket manufacturers like Connecticut Electric produce UL-listed replacement breakers designed to fit legacy NB panelboards.
