Product FAQs
6 answersCan I install the CHB120 in a standard Eaton CH residential load center?
No. The CHB120 is a bolt-on circuit breaker designed for commercial Cutler-Hammer Type PB and Type PH panelboards. Standard CH load centers require plug-on breakers.
Are Eaton CHB and BAB circuit breakers interchangeable?
No. Although both are commercial bolt-on breakers made by Eaton, CHB and BAB series breakers have different physical dimensions and panel mounting requirements. They cannot be used interchangeably.
Is the CHB120 suitable for switching fluorescent lighting loads?
Yes. The CHB120 is SWD (Switching Duty) rated, meaning it is approved for switching 120V fluorescent lighting circuits on and off on a regular basis.
Does the CHB120 carry an HACR rating for HVAC equipment?
Yes. This breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires this specific overcurrent protection rating.
Does the CHB120 provide ground fault or arc fault protection?
No. This is a standard thermal-magnetic circuit breaker that provides long-time and instantaneous trip functions for overload and short-circuit protection. It does not offer GFCI or AFCI capabilities.
Can I use the CHB120 for a 240V appliance?
No. The CHB120 is a 1-pole breaker designed for 120V circuits. For a 240V appliance, you will need a 2-pole breaker from the CHB series, such as the CHB220.
