Product FAQs
7 answersWhat load centers are compatible with the BR335 circuit breaker?
The BR335 is designed for use in Eaton and Cutler-Hammer Type BR load centers. It is also UL-listed for use in specific legacy Westinghouse, Challenger, and Bryant panels that accept Type BR breakers.
Can the Eaton BR335 replace older Bryant or Westinghouse breakers?
Yes, the Eaton BR335 is the direct, UL-approved replacement for legacy Bryant BR335 and Westinghouse BR335 35-amp, 3-pole breakers.
How many panel spaces does the BR335 require?
As a 3-pole, 1-inch format breaker, the BR335 requires three standard 1-inch spaces in a compatible three-phase load center.
Does the BR335 provide GFCI or AFCI protection?
No, the BR335 is a standard thermal-magnetic circuit breaker. It provides overload and short-circuit protection but does not include Ground Fault Circuit Interrupter (GFCI) or Arc Fault Circuit Interrupter (AFCI) features.
What does the LI trip function mean on this breaker?
The LI designation indicates that the breaker uses a thermal-magnetic trip unit providing Long-Time (thermal) protection against mild overloads and Instantaneous (magnetic) protection against severe short circuits.
Is this breaker compatible with Challenger panels?
Eaton BR breakers are UL-classified to replace Challenger Type C breakers in many legacy Challenger load centers. Always verify your specific panel labeling to confirm Type BR or Type C compatibility.
What wire types are approved for the BR335 box lugs?
The box lugs accept 14 AWG to 4 AWG copper or aluminum conductors. When installing, ensure the wire is properly stripped and seated in the lug before torquing to the manufacturer specifications found on the breaker label.
