Product FAQs
8 answersWhat panelboards are compatible with the EH2080 circuit breaker?
The EH2080 is designed for use in Eaton Pow-R-Line panelboards, switchboards, and motor control centers that accept legacy Westinghouse E-Frame bolt-on breakers.
Is the Eaton EH2080 the same as the Westinghouse EH2080?
Yes. Eaton acquired Westinghouse's distribution equipment business, so the Cutler-Hammer or Eaton EH2080 is the exact same legacy E-Frame breaker as the original Westinghouse model.
What wire sizes are approved for the lugs on the EH2080?
The factory-installed lugs on this breaker accept 4 AWG to 2/0 AWG wire. Both aluminum and copper conductors are permitted.
Can the EH2080 be used in direct current (DC) applications?
Yes, this thermal-magnetic breaker is rated for DC systems, providing up to 10kAIC of interrupting capacity at 250VDC.
What does the LI trip function mean on this breaker?
The LI designation indicates that the breaker provides Long-Time and Instantaneous trip functions. This is the standard thermal-magnetic protection profile for safeguarding circuits against both gradual overloads and sudden short circuits.
What is the modern replacement for the legacy EH2080 breaker?
The Eaton Series C EHD2080 is the modern F-Frame equivalent for the legacy EH2080. However, verify your panel's mounting requirements, as older motor control center buckets or panelboards may require specific retrofit kits for newer frames.
Does the EH2080 mount by plugging in or bolting on?
This breaker features a bolt-on connection type. It must be securely bolted to the busbar in compatible panelboards or switchboards, ensuring a rigid and reliable electrical connection.
Are the thermal and magnetic trip settings adjustable on the EH2080?
No, this breaker features fixed thermal and fixed magnetic trip settings. The trip curve is factory-calibrated for 80-amp applications and cannot be modified in the field.
