Description
Built for high-density circuit protection, the Eaton CHNT2020 tandem breaker delivers two independent 20A circuits from a single 3/4-inch pole space. This configuration is essential for adding capacity to fully populated enclosures. As a non-CTL replacement, it installs into pre-1968 Eaton and Cutler-Hammer Type CH load centers and serves as a direct substitute for the CHT2020. Rated at 10 kAIC for 120/240VAC, it is both HACR and SWD rated for fluorescent lighting applications.Specifications

Product FAQs
7 answersWhat is the difference between the CHNT2020 and the CHT2020?
The CHNT2020 is a Non-CTL (Circuit Total Limiting) breaker designed for older, pre-1968 Eaton and Cutler-Hammer Type CH load centers. The CHT2020 is a CTL breaker with a rejection clip designed for newer panels.
Can I use the CHNT2020 in a modern Eaton CH load center?
No. Modern Eaton CH load centers require CTL breakers like the CHT2020, which feature a physical rejection clip. The CHNT2020 is strictly for replacement use in older, Non-CTL panels.
Does the CHNT2020 have a rejection clip?
No. As a Non-CTL breaker, the CHNT2020 does not include a rejection clip. It is designed to fit into any standard 3/4-inch space in compatible pre-1968 Type CH panels.
Is the CHNT2020 rated for switching duty?
Yes, this breaker is SWD (Switching Duty) rated, meaning it can be used to switch 120V fluorescent lighting loads on and off on a regular basis.
Is this breaker HACR rated?
Yes, the CHNT2020 is HACR rated for use with heating, air conditioning, and refrigeration equipment that requires this specific protection.
How much panel space does the CHNT2020 require?
This tandem breaker provides two independent 20A circuits while only occupying a single 3/4-inch pole space in the load center.
Are there any National Electrical Code (NEC) restrictions for installing the CHNT2020?
Yes. Per NEC requirements, Non-CTL breakers like the CHNT2020 are restricted to replacement use only in older panels built before 1968. They cannot be used to add circuits to newer panels that require CTL breakers.
