Product FAQs
7 answersWhat equipment is compatible with the FS340100A circuit breaker?
This Series C F-Frame breaker is designed to bolt onto Eaton panelboards, switchboards, motor control centers, and industrial enclosures.
What wire sizes are supported by the standard lugs on the FS340100A?
The included line and load lugs accept copper or aluminum conductors ranging from 14 AWG to 1/0 AWG. Ensure proper torque specifications are followed during installation.
Does the FS340100A require a specific mounting hardware kit?
As a bolt-on molded case circuit breaker, it mounts directly to the bus of compatible Eaton Series C panelboards. Individual enclosure mounting may require a separate pre-drilled mounting panel.
Can the trip curve on the FS340100A be adjusted in the field?
No, this breaker is equipped with a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous (LI) trip functions are factory set and cannot be modified.
Why is the FS340100A suitable for both AC and DC applications?
Because it utilizes a thermal-magnetic trip unit rather than an electronic trip unit, it can effectively protect both alternating current and direct current circuits, including 250VDC systems.
What are the upgrade options if my panel requires a higher interrupting rating than the FS340100A provides?
The FS340100A delivers 14kAIC at 480VAC. If your fault current calculations require a higher rating in the same F-Frame footprint, you will need to source an FD, HFD, or FDC series breaker.
What are the standard safety procedures for installing this F-Frame breaker?
Always verify that the panelboard or switchboard is fully de-energized and locked out before installing the breaker. Verify that the available fault current does not exceed the 14kAIC rating at 480VAC before energizing the circuit.
