CHH2225H4 - 225Amp Circuit Breaker

CHH2225H4 - 225 Amp Circuit Breaker

The CHH2225H4 molded case circuit breaker is designed for dependable overcurrent protection in electrical distribution systems operating up to 240VAC. Built on the CHH4 frame and rated at 225 amperes, this 2-pole circuit breaker helps protect circuits and connected equipment from overloads and short circuits. Its 42kA interrupting capacity at 240VAC supports use in systems where higher fault current levels may be present. The breaker features a non-interchangeable trip unit, meaning the trip characteristics are factory-configured as part of the breaker assembly for consistent protection settings. Constructed to meet the form, fit, and function requirements expected in compatible electrical panels and switchgear, the CHH2225H4 is commonly used as a direct replacement in existing installations where matching electrical ratings and frame type are required. These molded case circuit breakers are built to last and designed to maintain dependable protection in legacy electrical systems when properly installed and maintained.
