Product FAQs
7 answersWhat panels are compatible with the UBIF250 circuit breaker?
This breaker is designed exclusively for use in Federal Pacific Electric (FPE) Stab-Lok load centers. It is not interchangeable with other panel brands.
Which Federal Pacific Electric breaker does the UBIF250 replace?
The UBIF250 (or UBIF250N) is a direct replacement for the original FPE NA250 circuit breaker. It features the same thick-series Type NA profile.
Can I use this breaker in place of a thin-series FPE breaker?
No. The UBIF250 is a Type NA thick-series breaker requiring 2 inches of panel space. It will not fit in slots designed exclusively for Type NC thin-series breakers.
What is the physical width of this 2-pole breaker?
As a thick-series Type NA replacement, it measures 1 inch per pole, making the total width of the breaker 2 inches.
Is the Connecticut Electric UBIF250 tested to modern safety standards?
Yes, it is ETL listed and conforms to UL 489 standards specifically for safe use as a replacement breaker in older Federal Pacific Stab-Lok panels.
Is there a difference between the UBIF250 and UBIF250N catalog numbers?
No, they represent the same 50-amp thick-series breaker. The N suffix is simply used by Connecticut Electric to denote their newer production runs and retail packaging.
Does this breaker require a specific mounting method?
It uses the proprietary Stab-Lok plug-on mounting design required by Federal Pacific panels. Ensure the panel busbar stabs are clean and undamaged before pressing the breaker into place.
