Part of the classic FPE lineup, the NB111030 is a 30A, 1-pole molded case circuit breaker built for 120VAC commercial applications. It delivers reliable thermal-magnetic protection for aging electrical systems without requiring panel upgrades. This breaker mounts seamlessly into legacy Federal Pacific NB and NBLP panelboards. When a modern substitute is required, the UBIF30NB serves as a direct cross-reference.Specifications

Product FAQs
6 answersWhich panelboards are compatible with the Federal Pacific NB111030?
This breaker is designed as an exact fit for legacy Federal Pacific NB and NBLP series panelboards.
Can the NB111030 be installed in standard Federal Pacific Stab-Lok residential load centers?
No. This is a bolt-on molded case circuit breaker designed specifically for NB and NBLP commercial panelboards. It will not fit in plug-on Stab-Lok residential panels.
How does the NB111030 connect to the panel?
It features a bolt-on mounting style, meaning it fastens directly to the panel busbar with screws to ensure a secure, stable connection in commercial applications.
What wire gauge range is supported by the terminals on this breaker?
The load side lugs are designed to accommodate aluminum or copper wire sizes ranging from 14 AWG to 2 AWG.
Is there a modern cross-reference for the Federal Pacific NB111030?
Yes, if a modern substitute is required, the UBIF30NB is manufactured as a direct replacement for this 30-amp, 1-pole legacy breaker.
What does the LI trip function code indicate on this breaker?
The LI designation means the breaker is equipped with Long-Time and Instantaneous trip functions. The long-time thermal element protects against gradual overloads, while the instantaneous magnetic element responds immediately to short circuits.
