CA3175W - 175Amp Circuit Breaker

CA3175W - 175Amp Circuit Breaker

When you need a 175 Amp, 3-pole Type CA circuit breaker, getting the right fit matters just as much as the electrical rating. The CA3175W molded case circuit breaker is designed for applications that require a breaker with a 175A rating, 10kA interrupting capacity at 240VAC, and a non-interchangeable trip unit. Whether you're replacing a failed breaker during maintenance or sourcing a matching unit for existing equipment, verifying the original specifications is critical to keeping your electrical distribution system operating as intended.

Built for commercial and industrial power distribution systems, the CA3175W features a compact molded case design with dimensions of 4.13" wide, 6.50" high, and 2.69" deep. The breaker is rated for operation in ambient temperatures up to 40°C (104°F) and is supplied without lugs installed, making it suitable for installations where lugs are specified separately or existing hardware will be reused. Its 3-pole configuration makes it a practical choice for many three-phase electrical systems found in manufacturing facilities, warehouses, commercial buildings, schools, and other demanding environments.

Electrical equipment is often expected to remain in service for decades. That's why finding a breaker that matches the original form, fit, and function is so important. The CA3175W is built to last and provides the ratings and configuration needed for compatible equipment designed around the Type CA platform.
