CAH3225Y - 225Amp Circuit Breaker

CAH3225Y - 225 Amp Circuit Breaker

The CAH3225Y molded case circuit breaker is a 225-amp, 3-pole breaker designed to provide dependable overcurrent protection in commercial and industrial electrical distribution systems. Built on a CAH frame with a non-interchangeable trip unit, this breaker is rated for 22kA at 240VAC, making it suitable for applications where reliable interruption capacity is required. Engineered for operation at 40°C, the CAH3225Y includes line-side lugs for straightforward installation and secure conductor termination. Its form, fit, and function align with legacy CAH-frame systems, making it a practical replacement solution for maintaining existing equipment without system redesign.

This molded case circuit breaker is built to last and designed to help protect conductors and connected equipment from overloads and short circuits. With a solid construction and clearly defined ratings, the CAH3225Y offers the electrical protection professionals expect in panelboards, switchboards, and distribution equipment operating within its specified limits.
