CHH3225H4 - 225Amp Circuit Breaker

CHH3225H4 - 225 Amp Circuit Breaker

The CHH3225H4 molded case circuit breaker is designed for use in electrical distribution systems that require dependable circuit protection and compatibility with CHH4 frame equipment. Rated at 225 amps with a 42kA interrupting capacity at 240VAC, this 3-pole breaker helps protect conductors and equipment by interrupting overcurrent and short-circuit conditions. Built with a non-interchangeable trip unit, the CHH3225H4 maintains a fixed trip configuration that supports consistent protection in systems originally designed for this breaker type. Its molded case construction and solid internal components reflect the long-lasting build typical of breakers used in commercial and industrial electrical panels. For facilities maintaining or servicing existing distribution systems, the CHH3225H4 provides the correct form, fit, and function replacement for compatible installations while maintaining the electrical ratings required for safe operation.
