Product FAQs
4 answersHow many panel spaces does the BJ2125 require?
The BJ2125 requires four 1-inch pole spaces. It is designed to span both sides of the bus bar, occupying two spaces on the left side and two spaces on the right side of the load center.
Can I install the BJ2125 in any Eaton BR load center?
No. According to Eaton specifications, the BJ2125 requires at least a 150A rated load center to safely accommodate the breaker.
Do I need a hold-down kit when using the BJ2125 as a main breaker?
Yes. If you are installing the BJ2125 as a back-fed main breaker or service disconnect, a hold-down kit is required to secure it to the load center bus bar.
Is the Eaton BJ2125 a direct replacement for older Bryant or Westinghouse breakers?
Yes. Eaton manufactures the BJ2125 to directly replace legacy Bryant and Westinghouse BJ2125 main and branch circuit breakers.
