Description
High-capacity commercial applications depend on the 22kAIC rating of this 80-amp thermal-magnetic breaker. Operating at 120/240VAC, it handles elevated fault currents in demanding industrial environments. The unit mounts into Federal Pacific NBLP, NBC, NBDP, and CDP panelboards, providing an exact physical match for aging systems. Note that while the UBIF280NB is listed as a substitute, it only offers a 10kA rating, making this original high-interrupting version critical for specific panels.Specifications

Product FAQs
4 answersWhich panelboards are compatible with the NB80H circuit breaker?
This bolt-on breaker is designed for use in Federal Pacific NBLP, NBC, NBDP, and CDP commercial panelboards. It provides an exact physical match for these aging systems without requiring aftermarket adapters.
Is there a modern substitute for the Federal Pacific NB80H?
The UBIF280NB is a modern substitute that fits the same panels. However, the UBIF280NB only offers a 10kAIC rating, making the original NB80H necessary for systems that require a high-interrupting 22kAIC rating.
What does the H signify in the NB80H catalog number?
The H indicates that this is a high-interrupting circuit breaker. While a standard NB80 has a 10kAIC rating, the NB80H is rated for 22kAIC at 240V to handle elevated fault currents in demanding industrial environments.
Does the NB80H use the Stab-Lok connection type?
No, the NB80H is a bolt-on commercial circuit breaker. It does not use the plug-on Stab-Lok design found in residential Federal Pacific load centers.

Had a project at a school built in the 1960’s and thought we were up a creek when confronted with ancient FPE commercial panels. Luckily we found what we needed with Suoerbreakers.
