Product FAQs
7 answersWhat panels and enclosures are compatible with the BWH2175?
This main breaker is designed for use in compatible Eaton Type BR load centers, ECB unit enclosures, meter stacks, and meter breakers.
What is the difference between the Eaton BW2175 and BWH2175?
The primary difference is the interrupting capacity. The BW2175 is rated at 10 kAIC, while the BWH2175 features a higher 25 kAIC rating for systems with higher available fault current.
What wire sizes are accepted by the lugs on this breaker?
The factory lugs accept 2 AWG to 300 kcmil copper or aluminum wire.
How does the BWH2175 mount into the panel?
It features a bolt-on connection, meaning it must be securely bolted to the panel busbars rather than snapping into place like a standard plug-on branch breaker.
What does the 25 kAIC rating indicate for this main breaker?
It means the breaker can safely interrupt up to 25,000 amps of fault current at 120/240V. This makes it suitable for residential and light commercial services where the utility transformer provides higher fault currents than a standard 10 kAIC breaker can handle.
Can this replace an older Cutler-Hammer BWH2175?
Yes. Eaton acquired Cutler-Hammer and continues to manufacture this breaker under the Eaton brand. It is a direct replacement for legacy Cutler-Hammer BWH2175 main breakers.
Can the BWH2175 be used as a standard branch breaker?
No, the BWH frame is specifically designed to function as a main breaker or sub-feed main in compatible Eaton enclosures and meter stacks.
