Eaton / Cutler-Hammer BW2200 Molded Case Circuit Breaker

This main breaker is designed specifically for 200-amp Eaton and Cutler-Hammer Type BR load centers, as well as Type ECB unit enclosures. Always verify your panel label to confirm it accepts Type BW main breakers.

Although it features a plug-on mounting style for the electrical connection, it requires a mechanical connection to the panel bus. It secures in place using the included mounting screws and two bus torque nuts to ensure a safe, reliable installation.

Both share the exact same physical footprint and 200-amp rating, but the BWH2200 features a higher interrupting capacity of 25 kAIC. The BW2200 is rated for standard 10 kAIC applications.

Yes, Eaton CSR and BW breakers share the same physical footprint and are generally interchangeable. However, you must ensure that your specific load center publication lists Type CSR as an acceptable main breaker before substituting.

Standard thermal-magnetic breakers like this one are typically rated for continuous loads up to 80 percent of their maximum capacity. For a 200-amp breaker, the continuous load should not exceed 160 amps to prevent nuisance tripping and overheating.

The LI designation indicates that the breaker provides both Long-Time and Instantaneous trip functions. The long-time function protects against sustained overloads, while the instantaneous function trips immediately during a severe short circuit.

Yes, the factory-installed lugs are rated for both aluminum and copper conductors. When using aluminum wire, it is highly recommended to apply a specialized joint compound to prevent oxidation and ensure a secure connection.

No, the BW series is specifically designed to function as a main circuit breaker or primary disconnect. It is not intended for use as a standard branch circuit breaker within the panel distribution section.
