Description
Designed to maintain aging infrastructure, the Federal Pacific NF631060 delivers 60-amp overcurrent protection for commercial facilities. This N-frame breaker features a fixed thermal-magnetic trip unit. It mounts into legacy Federal Pacific NF panelboards, serving as an exact fit replacement for discontinued components. Facility managers can utilize this unit to restore power safely, cross-referencing with substitute UBIF260N. Rated for 25kAIC at 240VAC, it handles demanding fault currents.Specifications

Product FAQs
6 answersWhat equipment is the Federal Pacific NF631060 designed to fit?
This 3-pole breaker is engineered exclusively for legacy Federal Pacific NF panelboards. Its bolt-on mounting configuration allows maintenance teams to replace failed components directly without modifying the existing busbar or using retrofit hardware.
What frame size is the NF631060 built on?
It is built on the Federal Pacific HF frame, which falls under the broader N Frames group. This specific frame footprint ensures proper alignment with the bolt-on mounting points in compatible NF series enclosures.
What type of trip unit is installed in the NF631060?
It utilizes a fixed thermal-magnetic trip unit with standard LI (Long-Time and Instantaneous) protection. Because both the thermal and magnetic elements are fixed, no field calibration or trip curve adjustments are required during installation.
What conductor sizes are supported by the NF631060 terminals?
The standard load-side lugs accept wire gauges from 14 AWG up to 1/0 AWG. Electricians should verify that the selected wire size meets NEC ampacity requirements for a 60A continuous load before terminating.
How does the interrupting rating of the NF631060 scale with system voltage?
The fault current tolerance decreases as system voltage increases. It provides a maximum 25kAIC at 240VAC, drops to 18kAIC at 480VAC, and offers 14kAIC for 600VAC commercial or industrial distribution systems.
Are there specific safety considerations when replacing Federal Pacific NF series breakers?
When servicing legacy Federal Pacific equipment, always verify the busbar condition before installing a replacement breaker. Ensure the panel is fully de-energized, as bolt-on connections require direct contact with the bus structure during mounting.
