CHB140 - 40Amp Circuit Breaker Description
CHB140 - 40 Amp Circuit Breaker
The CHB140 circuit breaker is a 1-pole, 40-amp bolt-on breaker designed for use in CHB frame panelboards and load centers operating at 120VAC. Rated at 10kA A.I.C., this breaker provides dependable overcurrent protection for branch circuits in commercial and industrial electrical distribution systems. Its bolt-on mounting configuration ensures a secure mechanical and electrical connection to the panelboard bus, helping maintain proper contact and consistent performance over time. Built to last and engineered for precise fit and function, the CHB140 is an ideal form, fit, and functional replacement for compatible CHB frame installations requiring a 40A single-pole breaker.
Whether you’re maintaining an existing electrical system, replacing a faulty breaker, or restoring a panel to safe working condition, the CHB140 offers the ratings and compatibility needed to keep operations running smoothly while meeting established electrical standards.
