CHB120 - 20Amp Circuit Breaker Description
CHB120 - 20 Amp Circuit Breaker
The CHB120 circuit breaker is a 1-pole, 20-amp bolt-on breaker designed for use in CHB frame panelboards operating at 120VAC with a 10kA A.I.C. rating. Built for dependable circuit protection in commercial and industrial electrical distribution systems, this breaker provides thermal-magnetic trip protection to help safeguard branch circuits from overloads and short circuits. Its bolt-on mounting style ensures a secure connection to the bus, helping maintain proper contact and consistent performance in compatible panelboards. Designed to meet original form, fit, and function requirements, the CHB120 is well suited for maintaining or servicing existing electrical systems that require a 20A, 1-pole solution within the CHB series.
