CSR2225N - 225Amp Circuit Breaker

CSR2225N - 225Amp Circuit Breaker

When reliable service entrance protection matters, the Eaton CSR2225N Main Circuit Breaker is built to handle the job. Rated at 225 amps and designed as a two-pole main breaker, this unit serves as the primary disconnect for compatible electrical systems while helping protect wiring and connected equipment from overloads and short-circuit conditions. Whether you're replacing an existing breaker, upgrading service equipment, or completing a new installation, the CSR2225N provides the ampacity and protection required for demanding residential and light commercial applications.

Designed for use in Type ECC Unit Enclosures, the Eaton CSR2225N combines a compact footprint with a 25 kAIC interrupting rating, helping provide protection during high fault-current events. The breaker accepts conductor sizes ranging from #2 AWG to 300 kcmil, making it easier to match existing wiring configurations during service upgrades and replacement projects. As part of Eaton's CH-family electrical equipment, it is intended for applications where maintaining proper equipment compatibility is an important part of the installation.

For electricians, contractors, and maintenance professionals, selecting the correct main breaker is about more than just amperage. The CSR2225N provides the combination of enclosure compatibility, fault-current protection, and conductor flexibility needed for a straightforward installation. Its UL 489 listing and Eaton-backed quality make it a practical choice for projects requiring a 225A main circuit breaker in a 120/240V electrical system.
