CA3125 - 125Amp Circuit Breaker

CA3125 - 125Amp Circuit Breaker

The CA3125 molded case circuit breaker is a 125 amp, 3 pole Type CA circuit breaker designed for use in commercial and industrial power distribution systems. When you're replacing an existing breaker, matching the original ratings and configuration is essential. The CA3125 provides a direct form, fit, and functional replacement for compatible Type CA installations, helping you maintain the integrity of existing electrical equipment without requiring modifications to the system.

Built with a non-interchangeable trip unit, the CA3125 features a 10kA interrupting capacity at 240VAC and includes both line-side and load-side lugs for installation convenience. Its three-pole design makes it suitable for a variety of three-phase electrical distribution applications where proper circuit protection and equipment compatibility are important. Rated for operation in ambient temperatures up to 40°C (104°F), this breaker is commonly found in panelboards, switchboards, and other electrical distribution equipment that continue to serve facilities across commercial and industrial environments.
