CA3225W - 225Amp Circuit Breaker

CA3225W - 225 Amp Circuit Breaker

The CA3225W is a 225 amp, 3-pole molded case circuit breaker built on a CA frame and rated for 10kA interrupting capacity at 240VAC. It’s designed for use in three-phase electrical distribution systems where dependable overcurrent protection is required. Calibrated at 40°C, this breaker provides consistent thermal-magnetic protection under standard operating conditions found in commercial and industrial facilities.

This model features a non-interchangeable trip unit, meaning the trip characteristics are factory-set and not field adjustable. It ships without lugs installed, allowing installers to configure terminations based on conductor size and application requirements. With its molded case construction and solid internal components, the CA3225W is built to last and intended for direct form, fit, and function replacement in compatible equipment using the CA frame platform.

If you’re maintaining existing infrastructure and need a breaker that matches original specifications, this unit is designed to integrate properly into systems built around CA frame breakers.
