CHB150 - 50Amp Circuit Breaker

CHB150 - 50 Amp Circuit Breaker

The CHB150 circuit breaker is a 50 amp, single-pole, bolt-on breaker designed for use in CHB frame panelboards and distribution systems operating at 120VAC. Built to provide dependable branch circuit protection, this breaker is rated at 10kA A.I.C. at 120VAC, helping safeguard electrical systems from overloads and short circuits. Its bolt-on mounting design ensures a secure mechanical and electrical connection to the panelboard bus, making it a practical form, fit, and function replacement for compatible CHB installations. Compact in size and weighing approximately 0.75 lbs., the CHB150 is well-suited for commercial and light industrial environments where consistent circuit protection is required. Like all properly rated molded case circuit breakers, it is built to last and intended for long-term service within its specified ratings.
