Description
Restoring older commercial systems requires exact-fit components like this 80A bolt-on unit. Built for 120/240VAC applications, it provides reliable thermal-magnetic protection for aging infrastructure. It mounts into Federal Pacific NB and NBLP panelboards without requiring aftermarket adapters or modifications. When the original hardware fails, this component serves as a seamless replacement, though modern UBIF280NB substitutes are also available for these 10kA rated circuits.Specifications

Yes, Connecticut Electric manufactures an ETL-listed replacement for this breaker under the catalog number UBIF280NB, which is designed to fit the same NB and NBLP panelboards.
What wire sizes do the lugs on the NB80 accept?
