Description
A seamless replacement for legacy industrial systems, the FCL3020 is a 20-amp, 3-pole current limiting molded case circuit breaker from Eaton. It provides robust thermal-magnetic protection for commercial facilities. This unit-mount breaker installs into Eaton Series C panelboards and motor control centers. It serves as an exact cross-reference for older Westinghouse F-Frame installations. Rated 150 kAIC at 480VAC, its current-limiting design restricts let-through energy during a fault.Specifications

Product FAQs
6 answersIs the Eaton FCL3020 a direct replacement for older Westinghouse FCL3020 breakers?
Yes. Eaton acquired the Westinghouse distribution equipment line, and the modern Eaton FCL3020 serves as an exact cross-reference for legacy Westinghouse F-Frame FCL3020 installations. It shares the same physical footprint and electrical characteristics.
What is the benefit of the current limiting design on the FCL3020?
As a current limiting breaker, the FCL3020 clears short circuits extremely fast, restricting the peak let-through current and energy. This reduces thermal and magnetic stress on downstream components during a fault event.
Are retrofit kits required when installing the FCL3020 into vintage panelboards?
While the FCL3020 fits standard F-Frame footprints, installing it into certain legacy Westinghouse CDP or FDP panelboards, or older motor control center buckets, may require specific retrofit mounting kits or updated handle mechanisms.
Which electrical enclosures are compatible with the FCL3020?
This unit mount, bolt-on breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers. It is also backward compatible with many legacy Westinghouse enclosures built for F-Frame breakers.
What does the LI trip function code mean on the FCL3020?
The LI designation indicates that the thermal magnetic trip unit provides Long-Time (L) and Instantaneous (I) protection. The Long-Time function protects against sustained overloads, while the Instantaneous function provides immediate tripping during severe short circuits.
Can the trip settings on the FCL3020 be adjusted in the field?
No. The FCL3020 features a fixed thermal and fixed magnetic trip unit, meaning the overload and short circuit trip thresholds are factory set and cannot be modified by the user.
