Product FAQs
7 answersWhat equipment is the FS340070A circuit breaker designed to fit?
This Series C F-Frame breaker is compatible with Eaton Series C panelboards, switchboards, and industrial enclosures. It is not designed for standard residential load centers.
Can I use the FS340070A in a standard residential breaker box?
No, this is a commercial and industrial molded case circuit breaker. It will not fit in standard residential load centers that require miniature plug-on or bolt-on breakers.
Does the FS340070A plug onto a busbar or bolt into place?
This is a unit mount circuit breaker, meaning it bolts directly to the mounting pan or chassis of the enclosure rather than plugging onto a busbar.
What wire gauge is required for the terminals on this 70-amp breaker?
The factory-installed lugs accommodate wire sizes from 14 AWG up to 1/0 AWG. Ensure your conductors are properly sized for a 70A load according to the National Electrical Code.
Can the trip settings on the FS340070A be adjusted in the field?
No. This breaker is equipped with a thermal-magnetic trip unit that has fixed long-time and fixed instantaneous (LI) settings, meaning the trip curve cannot be modified.
Is the Eaton FS340070A the same as the Cutler-Hammer or Westinghouse version?
Yes. Eaton acquired the Cutler-Hammer and Westinghouse distribution equipment lines. An Eaton FS340070A is the exact same form, fit, and function as the legacy Cutler-Hammer or Westinghouse breakers sharing this catalog number.
What are the safety requirements for installing this Series C breaker?
Installation must be performed by a licensed electrician. Always de-energize the panelboard or switchboard completely and verify zero voltage before mounting or wiring the breaker to prevent arc flash and shock hazards.
