Product FAQs
5 answers
How many panel spaces does the BJ2175 require?
This breaker requires four 1-inch spaces total. It occupies two spaces on the left side and two spaces on the right side of the load center bus.
What is the difference between a standard BR breaker and a BJ breaker?
Standard two-pole BR breakers occupy two panel spaces, while two-pole BJ breakers are wider and require four spaces across the panel bus. BJ frames are typically used for higher amperage applications from 150A to 225A.
Do I need a hold-down kit when using the BJ2175 as a main breaker?
Yes. If you are installing this breaker as a back-fed main in a Main Lug Only (MLO) load center, safety codes require a hold-down screw kit, such as the Eaton BJHDS, to secure the breaker to the panel bus.
Can I use this breaker to replace older Bryant or Westinghouse models?
Yes. Eaton acquired the Cutler-Hammer, Bryant, and Westinghouse breaker lines. The BJ2175 is the direct functional replacement for legacy Bryant and Westinghouse BJ2175 breakers.
What size load center is required for this breaker?
The BJ2175 must be installed in an Eaton BR or legacy Westinghouse or Bryant load center rated for at least 150 amps.
