Product FAQs
7 answersWhat enclosures and panelboards are compatible with the FDB3110L?
This Series C F-frame breaker is designed for use in Eaton F-frame enclosures, switchboards, and motor control centers.
Can I use the FDB3110L in place of an FD or HFD breaker?
Yes, the FDB, FD, and HFD breakers share the same physical dimensions. However, the FDB is the standard interrupting capacity version, rated at 14kA at 480VAC. Ensure this interrupting rating meets or exceeds your system fault current before substituting.
Does the Eaton FDB3110L replace older Westinghouse breakers?
Yes, Eaton acquired the Westinghouse molded case circuit breaker line. The Series C FDB3110L is a direct replacement for the legacy Westinghouse FDB3110L.
Does the FDB3110L come with lugs installed?
Yes, the L in the catalog number indicates that this breaker includes factory-installed line and load lugs, which accept 4 AWG to 4/0 AWG copper or aluminum wire.
What is the recommended torque for the line and load lugs?
The standard 3TA225FD aluminum lugs for 4 AWG to 4/0 AWG wire should be torqued to 120 lb-in using a 3/16-inch hex wrench.
Is the FDB3110L suitable for reverse feed applications?
Yes, standard thermal-magnetic Series C F-frame breakers are suitable for reverse feed applications.
Is the FDB3110L HACR rated?
Yes, all Series C F-frame breakers are HACR rated for use with heating, air conditioning, and refrigeration equipment.
