Product FAQs
5 answersWhat load centers are compatible with the CHN240GF?
This breaker is designed exclusively for Eaton and Cutler-Hammer Type CH load centers. It features the standard 3/4-inch per pole format and will not fit in Type BR or other 1-inch panelboards.
Is the CHN240GF a direct replacement for the CH240GF?
Yes. The CHN240GF replaces older Cutler-Hammer and Eaton catalog numbers CH240GF and CH240GFT.
Does this breaker require a plug-on neutral panel?
No. While it is listed for use in Type CH Plug-On Neutral load centers, this specific model utilizes a pigtail neutral wire. The pigtail must be routed and connected directly to the neutral bar, allowing installation in both legacy and modern CH panels.
What level of ground fault protection does this breaker offer?
It provides Class A 5mA ground fault protection for personnel. This makes it suitable for residential and commercial applications requiring life-safety GFCI capabilities, such as pools, spas, and outdoor equipment.
What does the LIG trip function indicate for this breaker?
The LIG designation means the breaker combines Long-Time and Instantaneous trip functions for standard thermal-magnetic overcurrent and short-circuit protection, along with integrated Ground-Fault sensing.
