CA3175Y - 175Amp Circuit Breaker

CA3175Y - 175 Amp Circuit Breaker

The CA3175Y circuit breaker is a 3-pole, 175-amp molded case circuit breaker designed for dependable overcurrent protection in commercial and industrial electrical distribution systems. Built on a CA frame with a non-interchangeable trip unit, this breaker provides consistent thermal-magnetic protection in applications operating up to 240VAC with a 10kA A.I.C. rating. Rated for use at 40°C, the CA3175Y is engineered to maintain proper circuit protection under standard ambient conditions commonly found in electrical rooms and equipment enclosures. Line-side lugs are included, helping ensure proper conductor termination and secure installation. Designed for long-term service, this breaker delivers the form, fit, and function required for maintaining or restoring compatible legacy power distribution systems.

Whether you’re replacing an existing CA frame breaker or maintaining facility infrastructure, the CA3175Y offers a direct, code-aligned solution for branch and feeder circuit protection where 175-amp capacity is required.
