CAH2150Y - 150Amp Circuit Breaker

CAH2150Y - 150 Amp Circuit Breaker

The CAH2150Y molded case circuit breaker is a 2-pole, 150-amp breaker designed to provide 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 performance at 40°C, helping protect conductors and equipment from overloads and short circuits. With a 22kA A.I.C. rating at 120/240VAC, the CAH2150Y is suited for applications requiring a higher interrupting capacity within compatible panelboards and switchboards. Line-side lugs are included, supporting secure conductor termination and proper installation. For facilities maintaining or servicing existing electrical infrastructure, this breaker offers the correct form, fit, and function to match specified CAH frame systems.

Designed for durability and long service life, the CAH2150Y molded case circuit breaker is commonly used in commercial and industrial environments where reliable branch or feeder circuit protection is essential. Its compact footprint and 2-pole configuration make it suitable for a wide range of distribution setups that require 150-amp protection within the CAH frame class.
