CHB240 - 40Amp Circuit Breaker

CHB240 - 40 Amp Circuit Breaker

The CHB240 circuit breaker is a 2-pole, 40-amp, bolt-on style breaker designed for use in electrical distribution systems operating at 120/240VAC. Built on the dependable CHB frame platform, this breaker provides thermal-magnetic overcurrent protection to help safeguard branch circuits from overloads and short circuits. With a 10kA A.I.C. rating, the CHB240 is engineered for use in compatible panelboards and load centers where this interrupting capacity is specified. Its bolt-on mounting style ensures a secure mechanical and electrical connection, making it a practical form, fit, and function replacement for existing CHB series installations. Built to last and manufactured to meet applicable industry standards, the CHB240 is well-suited for maintaining and servicing legacy electrical systems in commercial and industrial environments.
