CHB330 - 30Amp Circuit Breaker

CHB330 - 30 Amp Circuit Breaker

The CHB330 circuit breaker is a 3-pole, 30-amp bolt-on breaker designed for use in CHB frame panelboards and distribution equipment. Rated for 10kA at 240VAC, this breaker provides dependable overcurrent protection for commercial and industrial electrical systems operating within its specified ratings. Built for form, fit, and function compatibility, the CHB330 is engineered to integrate seamlessly into existing CHB-style installations. Its bolt-on mounting configuration ensures a secure connection to the panelboard bus, helping maintain stable electrical contact and consistent performance over time. Designed to last and manufactured to meet applicable industry standards, this breaker is well suited for maintaining and servicing established electrical systems where CHB frame devices are required.
