Engineered for industrial environments, this 60A breaker supplies essential overcurrent defense for legacy power distribution systems. It helps extend the operational life of original equipment. The unit mounts securely into Federal Pacific NBLP panelboards, offering a precise match for older enclosures. It acts as a reliable substitute for the NB160, avoiding complex retrofits. Delivering a 10kAIC capacity at 120VAC, the HACR-rated device includes fixed trip adjustability and load side lugs.
Which panelboards accept the Federal Pacific NB111060 circuit breaker?
This bolt-on breaker is specifically designed for installation in legacy Federal Pacific NBLP commercial panelboards.
Will the NB111060 fit in a Federal Pacific Stab-Lok load center?
No. The NB111060 is a commercial bolt-on breaker designed specifically for NBLP panelboards. It is not compatible with residential Stab-Lok load centers, which require plug-on connections.
What wire gauge and material can be used with the NB111060 terminals?
The load-side lugs are rated to accept 14 AWG to 2 AWG wire and are compatible with both aluminum (Al) and copper (Cu) conductors.
Does the NB111060 feature an adjustable trip setting?
No, this breaker utilizes a fixed thermal-magnetic trip unit. It provides standard long-time and instantaneous (LI) protection without field adjustability.
Is the NB111060 rated for 277V commercial lighting circuits?
No. This single-pole breaker is rated for 120VAC applications only, with a maximum interrupting capacity of 10kAIC. It is not suitable for 277V systems.
How does the NB111060 mount into the panelboard?
It features a bolt-on connection. The breaker must be mechanically fastened directly to the panelboard busbar, providing a secure contact for commercial applications.

Hard to find breakers
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.
