Product FAQs
8 answersWhat is the difference between the FD3100, HFD3100, and FDC3100 circuit breakers?
These breakers share the same physical dimensions and 100A rating within the Eaton Series C F-Frame family, but they have different interrupting capacities at 480VAC. The FD3100 is rated at 35kAIC, the HFD3100 at 65kAIC, and the FDC3100 provides the highest rating at 100kAIC.
What enclosures and panels are compatible with the FDC3100?
This unit-mount breaker is designed for use in Eaton Series C panelboards, switchboards, motor control centers, and standalone F-Frame enclosures.
What type of wire connections are included with the FDC3100?
This breaker comes equipped with load side lug terminals that accept 14 to 1/0 AWG copper or aluminum wire. Line side lugs or other terminal configurations must be sourced separately if required for your installation.
Can the FDC3100 be used in DC applications?
Yes, the FDC3100 is rated for up to 250VDC and provides a 22kA interrupting capacity for direct current systems.
Is the trip unit on the FDC3100 adjustable or interchangeable?
No, this breaker features a non-interchangeable thermal-magnetic trip unit with fixed long-time and instantaneous (LI) trip functions.
What internal accessories can be added to the FDC3100?
As a Series C F-Frame breaker, it accepts standard field-installable internal accessories such as shunt trips, undervoltage releases, auxiliary switches, and bell alarms.
How is the FDC3100 mounted in a panel?
This is a unit-mount, bolt-on circuit breaker. It secures directly to the panel or mounting surface using screws or bolts, rather than snapping onto a DIN rail or busbar.
Can the FDC3100 be reverse fed?
Yes, standard Eaton Series C F-Frame thermal-magnetic breakers like the FDC3100 are suitable for reverse feed applications.
