Product FAQs
4 answersWhich Cutler-Hammer panelboards accept the CHB2125 breaker?
It is engineered specifically for bolt-on installation in Cutler-Hammer Type PB and Type PH commercial panelboards, as well as compatible meter panels. It will not fit standard residential plug-on load centers.
Can I use a CHB2125 in place of a standard CH2125 breaker?
No. The CHB2125 is a bolt-on breaker designed for commercial PB and PH panelboards. The standard CH2125 is a plug-on breaker meant for residential CH load centers. They are not interchangeable.
How much physical space does the CHB2125 take up in a panel?
As part of the CH family, this 2-pole breaker requires two standard 3/4-inch spaces, resulting in a total mounted width of 1.5 inches.
Can the CHB2125 be used for HVAC applications?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment motor loads.
