Product FAQs

5 answers
Where can the FS340030A circuit breaker be installed?

This unit-mount F-Frame breaker bolts directly into Eaton Series C panelboards, switchboards, and standalone electrical enclosures rather than plugging into a busbar.

How do you wire the line and load connections on this breaker?

The breaker features a feed-thru connection and comes equipped with standard lugs on both ends. These terminals accept 14 AWG to 1/0 AWG copper or aluminum conductors.

Can field-installable accessories be added to this breaker?

Yes, Eaton Series C F-Frame breakers support a range of internal accessories, including shunt trips, auxiliary switches, bell alarms, and undervoltage releases.

What type of fault protection does the fixed thermal-magnetic trip unit provide?

The non-interchangeable trip unit provides long-time delay protection for sustained overloads and instantaneous magnetic trip functions to quickly clear short circuits.

Can the FS340030A replace legacy Cutler-Hammer circuit breakers?

Yes, it shares the standard F-Frame physical dimensions and can serve as a drop-in replacement for older Westinghouse or Cutler-Hammer breakers like the EHD3030 and FDB3030, provided the interrupting capacity meets your system requirements.
