Description
Restoring power to vintage commercial systems requires the Eaton EA2070, a 70A, 2-pole legacy molded case circuit breaker. It ensures robust overcurrent defense for 240VAC and 125/250VDC applications. Engineered as an exact bolt-on replacement, it fits perfectly into older Westinghouse and Cutler-Hammer panelboards. When upgrading panels, the EHD2070 serves as its modern substitute. This HACR-rated breaker features a 10kAIC interrupting capacity and a fixed thermal-magnetic trip unit.Specifications

Product FAQs
6 answersIs the Westinghouse EA2070 still manufactured?
No, the EA frame is an obsolete legacy product. If you need a modern substitute for panel upgrades, the Eaton EHD2070 serves as an exact bolt-on replacement.
What panels will accept the EA2070 breaker?
It is engineered to fit older Westinghouse E-frame panelboards. It can also be used as a retrofit component in compatible Eaton Cutler-Hammer panelboards.
Is the EA2070 rated for direct current (DC) systems?
Yes, in addition to its standard AC ratings, this breaker is certified for DC applications up to 125/250VDC, making it suitable for specific industrial control or battery circuits.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the thermal-magnetic trip unit provides Long-Time and Instantaneous protection. This ensures the breaker will trip on a delay for sustained overloads, while tripping immediately during a severe short circuit.
What is the proper way to secure the EA2070 in a panel?
This is a bolt-on breaker, meaning it must be mechanically fastened directly to the panelboard busbars. Ensure the panel is completely de-energized before bolting the breaker in place to prevent arc flash hazards.
What wire sizes are compatible with the EA2070 lugs?
The factory lugs on this breaker are designed to accept wire gauges from 14 AWG up to 1/0 AWG. Always verify that your conductor material and size align with local electrical codes for a 70-amp circuit.
