Product FAQs
7 answersWhat equipment is compatible with the FS240100A breaker?
This F-Frame breaker is designed for installation in Eaton Series C panelboards, switchboards, and motor control centers. It requires a bolt-on connection and is not compatible with standard residential plug-on load centers.
What frame size does the FS240100A use?
It is built on the Eaton Series C F-Frame platform, specifically utilizing the FS frame type. It shares physical dimensions and mounting footprints with other standard Eaton F-Frame breakers.
What wire sizes and materials do the terminals on the FS240100A accept?
The factory-installed lugs accommodate 14 AWG to 1/0 AWG conductors. They are dual-rated for use with both copper (Cu) and aluminum (Al) wiring.
How is the FS240100A mounted into an electrical panel?
It utilizes a unit-mount, bolt-on configuration. The breaker must be physically bolted to the bus or mounting pan, ensuring a secure connection in industrial or commercial environments.

The LI designation means the thermal-magnetic trip unit provides Long-Time (L) protection against gradual overloads and Instantaneous (I) protection against severe short circuits.
