Product FAQs
4 answersWhat is the difference between the Eaton CSH2225N and CSR2225N?
The CSH2225N and CSR2225N share the same physical dimensions and fit the same panels. The difference is the interrupting rating: the CSH2225N is rated at 35kAIC, while the CSR2225N is rated at 25kAIC.
Which load centers are compatible with the CSH2225N main breaker?
The CSH2225N is designed for use as a main breaker in compatible Eaton Type CH and Type BR load centers, as well as Type ECB unit enclosures that require a 225A CSR or CSH style main breaker.
Can the CSH2225N be used as a service disconnect?
Yes, when installed in a compatible load center or enclosure, this 225A main breaker can serve as the primary service disconnect for the electrical system.
Can a load center with a CSH2225N main breaker be inverted for bottom-feed applications?
Yes. Because the CSH2225N main circuit breaker handle operates horizontally, the panel can be rotated 180 degrees for straight-in wiring of bottom-feed power cables while remaining compliant with NEC Article 240.81 handle orientation requirements.
