Providing 100 amps of main service protection, this thermal-magnetic circuit breaker is rated for 25kAIC at 120/240VAC. It is designed to handle higher fault currents in both residential and commercial electrical systems. The unit installs into Eaton Type BR load centers, meter breakers, and ECB unit enclosures. It features standard lug terminals that accept 2 AWG through 300 kcmil conductors. With fixed long-time and instantaneous trip settings, it responds accurately to overcurrent events.

Product FAQs
5 answers
What is the difference between the Eaton BW2100 and BWH2100?
The BWH2100 features a high interrupting rating of 25 kAIC at 120/240V, while the standard BW2100 is rated for 10 kAIC. Both are 100A main breakers that share the same physical footprint and install into the same enclosures.
Which load centers and enclosures are compatible with the BWH2100?
This main breaker is designed to install into Eaton Type BR load centers, ECB unit enclosures, meter breakers, and group metering stacks.
Do I need a hold-down kit when installing this breaker?
If you are installing the BWH2100 as a back-fed main breaker in a load center or meter breaker, the National Electrical Code requires a hold-down kit to secure the breaker to the backpan. The specific kit part number depends on your panel model.
Can the BWH2100 replace older Cutler-Hammer main breakers?
Yes, it serves as a direct drop-in replacement for legacy Cutler-Hammer BW2100 and CM2100 units, provided your system requires a 100A main breaker with a 25 kAIC rating.
What type of protection does the BWH2100 provide?
It utilizes fixed thermal-magnetic trip technology. The thermal component provides long-time protection against gradual overloads, while the magnetic component offers instantaneous protection against short circuits.
