Product FAQs
5 answersWhich panelboards are compatible with the EA3020 circuit breaker?
This E-frame breaker is designed for installation in legacy Westinghouse CDP and FDP panelboards, as well as modern Eaton Pow-R-Line 3 distribution systems.
What is the modern Eaton replacement for the legacy Westinghouse EA3020?
The EA3020 can be directly replaced by the newer Eaton EHD3020 circuit breaker, which shares the same E-frame footprint for a drop-in replacement in existing panelboards.
Can the EA3020 be used in DC electrical systems?
Yes, this breaker is rated for DC applications up to 125/250VDC, providing a 5kAIC interrupting capacity for direct current circuits.
How does the EA3020 mount into the panelboard?
It features a bolt-on mounting configuration, securing directly to the busbars of compatible CDP, FDP, and Pow-R-Line 3 panelboards.
Does the EA3020 provide ground fault or arc fault protection?
No. The EA3020 is a standard thermal-magnetic breaker equipped with fixed long-time and instantaneous (LI) trip functions. It does not include GFCI or AFCI circuitry.
