Built to support older infrastructure, this 45-amp miniature breaker offers essential long-time and instantaneous trip functions. It is tailored for residential applications utilizing 120VAC circuits. The device mounts into classic Federal Pacific Stab-Lok panels, offering a precise match for original hardware.

Product FAQs
4 answersHow much panel space does the NC045 require?
The NC series features a thin, wafer-style construction. This single-pole breaker requires only one half-inch of space on the busbar, allowing for high-density configurations in compatible Stab-Lok enclosures.
What is the Connecticut Electric cross-reference for the NC045?
The UBIF045N is the direct aftermarket replacement manufactured by Connecticut Electric. It is designed to fit the same half-inch Stab-Lok panel slots as the original Federal Pacific NC045.
What wire sizes are compatible with the NC045 terminals?
The breaker lugs are rated for 14 AWG to 4 AWG copper or aluminum conductors. Always verify that your selected wire gauge meets local electrical codes for a 45-amp circuit.
How does the thermal-magnetic trip mechanism protect the circuit?
The fixed thermal-magnetic (LI) unit provides dual protection. The thermal element offers a long-time delay to handle temporary overloads without nuisance tripping, while the magnetic element provides instantaneous tripping during severe short circuits.

Was happy with all the service would’ve wished the person would inform me if I would’ve spent $15 more I could’ve got free shipping. That way I could’ve ordered another 20 amp circuit breaker. And got it for free.

I wasn't sure about ordering my particular breakers online because they don't make replica replacements but found the warranty outstanding. The follow-up call as a new customer and the speed with which my order was processed and completed was superior. The price was 1/3 what the ONE local supplier charged.
