Product FAQs
7 answersWhich panelboards are compatible with the EH2020 circuit breaker?
The EH2020 is designed specifically for Eaton Pow-R-Line panelboards, switchboards, and motor control centers. It fits legacy Westinghouse and Cutler-Hammer E-Frame enclosures requiring a bolt-on connection.
Can the EH2020 replace older Westinghouse or Cutler-Hammer breakers?
Yes, because Eaton acquired the Cutler-Hammer and Westinghouse distribution equipment lines, the Eaton EH2020 is a direct replacement for legacy EH-frame breakers from those brands. It can also serve as a substitute for the newer EHD2020 model in compatible systems.
What wire sizes and materials are compatible with the EH2020 lugs?
The breaker includes factory-installed lugs that accept both aluminum and copper (Al/Cu) wiring. The supported wire gauge range is 14 AWG to 1/0 AWG.
Is the EH2020 rated for direct current (DC) applications?
Yes, in addition to its AC ratings of 18kA at 240VAC and 14kA at 480VAC, the EH2020 is rated for DC applications with an interrupting capacity of 10kA at 250VDC.
Does the EH2020 require a specific mounting hardware kit?
The EH2020 is a bolt-on circuit breaker designed to bolt directly to the busbar of compatible Eaton Pow-R-Line panelboards and switchboards. Ensure the panel is de-energized before bolting the breaker into place.
Are the trip settings on the EH2020 adjustable?
No, the EH2020 features a fixed thermal-magnetic trip unit. Both the long-time overload and instantaneous short-circuit trip functions are factory-set and cannot be adjusted in the field.
What safety precautions should be taken before installing the EH2020?
Always ensure the main power to the panelboard or switchboard is completely de-energized and locked out before installing this bolt-on breaker. Installation should only be performed by a qualified electrician following local electrical codes.
