CA3125Y - 125Amp Circuit Breaker

CA3125Y - 125Amp Circuit Breaker

The CA3125Y is a 125 amp, 3-pole Type CA molded case circuit breaker designed for use in commercial and industrial electrical systems where matching existing equipment specifications is essential. Whether you're replacing a failed breaker, performing routine maintenance, or keeping an established power distribution system in service, having the correct breaker can save time and help avoid unnecessary modifications. This unit combines a 125A rating, 10kA interrupting capacity at 240VAC, and a non-interchangeable trip unit in a compact design commonly used in Type CA installations.

One detail that often matters during replacement projects is connection configuration. The CA3125Y includes line-side lugs, making it suitable for compatible equipment that requires that setup. Its three-pole design is commonly used in three-phase electrical distribution systems found in manufacturing facilities, warehouses, office buildings, schools, healthcare facilities, and other commercial environments. Instead of adapting the system to fit the breaker, many maintenance teams are looking for a breaker that matches the system already in place. That's where the CA3125Y fits. Built to last, it provides the form, fit, and functional compatibility needed for many existing Type CA applications.
