Product FAQs

7 answers
Can the Eaton BR240 be used to replace breakers in older Bryant or Westinghouse panels?

Yes. Eaton's Type BR circuit breakers are the direct UL-listed replacements for legacy Bryant, Westinghouse, and Challenger panels that accept 1-inch plug-on breakers.

Will the BR240 fit into a Square D Homeline or Siemens load center?

No. The BR240 is designed specifically for Eaton Type BR load centers, as well as compatible legacy panels (Bryant, Westinghouse, Challenger). It is not UL-listed for use in Square D, Siemens, or Murray load centers.

How much panel space is required to install the BR240?

The BR240 is a 2-pole breaker with a standard 1-inch per pole footprint, requiring two adjacent 1-inch spaces in the load center.

Can I use aluminum wiring with this 40A breaker?

Yes. The BR240 features box lug terminals that are rated for both copper (Cu) and aluminum (Al) wire, accepting sizes from 14 AWG up to 4 AWG.

Is the BR240 HACR rated for HVAC applications?

Yes. Eaton 2-pole Type BR circuit breakers are HACR (Heating, Air Conditioning, and Refrigeration) rated, making them suitable for use with HVAC equipment requiring this specification.

Does this breaker require a separate handle tie for 240V circuits?

No. As a manufactured 2-pole breaker, the BR240 features an internal common trip mechanism and a factory-installed handle tie to ensure both ungrounded legs trip simultaneously during an overload or short circuit.

Does the BR240 provide ground fault (GFCI) or arc fault (AFCI) protection?

No. The BR240 is a standard thermal-magnetic circuit breaker providing overload and short-circuit protection only. It does not include AFCI or GFCI circuitry.
