Description
Providing a seamless retrofit solution, this 100-amp molded case breaker handles 600VAC commercial loads with proven thermal-magnetic trip technology. It fits into legacy Westinghouse panelboards, motor control centers, and Eaton Pow-R-Line C enclosures. Rated for 14kA at 480VAC, this F-Frame unit eliminates the need for retrofit kits or panel modifications. It replaces older discontinued units and cross-references with modern FDB3100 and FD3100 equivalents.Specifications

Product FAQs
7 answersCan I install the F3100PF in a modern Eaton panelboard?
Yes, in addition to legacy Westinghouse enclosures, this F-frame breaker is fully compatible with Eaton Pow-R-Line C panelboards and standard motor control centers.
Does the F3100PF come with mounting terminals?
Yes, this breaker includes standard lugs on both the line and load sides, ready to accept 14 AWG to 1/0 AWG conductors for immediate installation.
Is the F3100PF a suitable replacement for obsolete Cutler-Hammer F-frame breakers?
Yes, because Eaton acquired the Westinghouse and Cutler-Hammer distribution lines, this breaker serves as a direct drop-in replacement for equivalent legacy 100A, 3-pole F-frame units without requiring retrofit kits.
Is the trip unit on the F3100PF adjustable?
No, this breaker features a non-interchangeable thermal-magnetic trip unit with fixed thermal and fixed magnetic settings for its long-time and instantaneous (LI) trip functions. It cannot be adjusted in the field.
Will I need a retrofit kit to install this breaker in a vintage Westinghouse panel?
For standard F-frame footprints in compatible Westinghouse panelboards, this bolt-on breaker mounts directly to the bus without requiring specialized retrofit kits or panel modifications.
Can the F3100PF be used in DC electrical systems?
Yes, in addition to its standard AC ratings, this thermal-magnetic breaker is rated for use in 250VDC applications, providing up to 10kA of interrupting capacity for direct current circuits.
Is the F3100PF suitable for reverse feed applications?
Yes, this thermal-magnetic molded case circuit breaker supports reverse feeding, making it versatile for various commercial and industrial wiring configurations.
