Description
A drop-in replacement for aging systems, the Eaton E1020 delivers 20A of reliable circuit protection. It mounts seamlessly into legacy Westinghouse panelboards, Eaton Pow-R-Line enclosures, and AB De-Ion panels for commercial applications. Engineered with a bolt-on mounting style, it ensures a secure connection. For modern upgrades, this unit is officially replaced by the EHD1020 and can be substituted with the EB1020. Rated at 7 kAIC at 120VAC, it features fixed thermal-magnetic trips.Specifications

Product FAQs
6 answersWhich panelboards accept the E1020 circuit breaker?
This legacy E-frame breaker is designed to bolt directly into older Westinghouse panelboards, AB De-Ion panels, and modern Eaton Pow-R-Line enclosures without requiring panel modifications.
Is the Westinghouse E1020 still in active production?
No, the E1020 is an obsolete, legacy molded case circuit breaker. If you need a modern equivalent for an existing panel, the Eaton EHD1020 or EB1020 serve as direct drop-in replacements.
Is the E1020 suitable for direct current (DC) circuits?
Yes. In addition to its standard 120VAC rating, this breaker is rated for 125VDC applications, where it provides a 5kAIC interrupting capacity.
What type of wire can be used with the E1020 lugs?
The included load-side lugs accept both copper (Cu) and aluminum (Al) conductors ranging from 14 AWG to 1/0 AWG. This wide range accommodates standard 20A wiring as well as upsized conductors needed to mitigate voltage drop over long runs.
Does the E1020 snap into place or bolt on?
The E1020 is a bolt-on circuit breaker. It fastens directly to the panelboard bus with screws, ensuring a secure, vibration-resistant connection typical in commercial and industrial distribution panels.
What type of trip unit does the E1020 use?
It features a fixed thermal-magnetic trip unit. This provides standard LI (Long-Time and Instantaneous) protection against both sustained overloads and sudden short circuits.
