CA3225 - 225Amp Circuit Breaker

CA3225 - 225 Amp Circuit Breaker

The CA3225 molded case circuit breaker is a 225 amp, 3 pole breaker designed for dependable circuit protection in commercial and industrial electrical distribution systems operating at up to 240VAC. Built on the CA frame platform and calibrated for 40°C environments, this breaker features a non-interchangeable trip unit and includes both line- and load-side lugs for straightforward installation. With a 10kA interrupting capacity at 240VAC, the CA3225 provides reliable overcurrent protection for feeders and branch circuits where proper fault interruption and consistent performance are critical. Its solid construction and proven design make it well-suited for maintaining existing electrical infrastructure that requires a form, fit, and functional replacement within CA frame assemblies. Engineered to meet the practical demands of facility maintenance teams, electrical contractors, and plant engineers, the CA3225 breaker helps protect conductors and connected equipment from overloads and short circuits. Whether installed in panelboards, switchboards, or distribution equipment compatible with CA frame breakers, it delivers consistent operation in systems that depend on stable, code-compliant protection.
