CAH2150W - 150Amp Circuit Breaker

CAH2150W - 150 Amp Circuit Breaker

The CAH2150W molded case circuit breaker is a 2-pole, 150 amp breaker designed for dependable overcurrent protection in 120/240VAC electrical distribution systems. Built on the CAH frame platform, this breaker features a non-interchangeable trip unit calibrated for consistent thermal-magnetic protection at 40°C. With a 22kA A.I.C. rating at 120/240VAC, the CAH2150W is engineered to provide the interrupting capacity required for many commercial and industrial panelboard and switchboard applications. Designed for proper form, fit, and function, this breaker is well-suited as a direct replacement in compatible legacy systems where maintaining original equipment specifications is essential.

Manufactured as a molded case circuit breaker (MCCB), the CAH2150W helps safeguard electrical circuits from overloads and short circuits while maintaining system integrity. Its 2-pole configuration makes it appropriate for protecting single-phase circuits operating at standard North American voltages. Please note that this unit ships without lugs installed, allowing for application-specific termination hardware as required.
