CHH3225 - 225Amp Circuit Breaker

CHH3225 - 225 Amp Circuit Breaker

The CHH3225 molded case circuit breaker is designed to provide dependable circuit protection in electrical distribution systems where higher interrupting capacity and stable operation are required. Built on the CHH frame and rated at 225 amps, this 3-pole circuit breaker helps protect equipment and conductors from overloads and short circuits in commercial and industrial power systems. Its non-interchangeable trip unit ensures that the calibrated trip characteristics remain consistent with the breaker’s design, supporting predictable operation in systems that rely on fixed protection settings. Molded case circuit breakers like the CHH3225 have long been used in panelboards, switchboards, and distribution equipment because they are built to last and maintain dependable protection over years of service. With a 100kA interrupting capacity at 240VAC, this breaker is suited for applications where fault current levels require a higher A.I.C. rating while maintaining proper form, fit, and function within compatible CHH-frame installations.
