Originally manufactured by Westinghouse and Cutler-Hammer, the FB2060 provides 60 amps of overcurrent protection for commercial and industrial applications. This bolt-on MCCB mounts into legacy Pow-R-Line C panelboards, FDP panelboards, and motor control centers. For modern upgrades, it can be replaced by the Eaton FDB2060 or FD2060 models. Rated at 14 kAIC at 480VAC, it features fixed thermal-magnetic trip settings and reverse feed capability for versatile installation.
Which panelboards are compatible with the Eaton FB2060?
This F-frame breaker is designed for installation in legacy Westinghouse and Cutler-Hammer Pow-R-Line C panelboards, FDP panelboards, switchboards, and motor control centers.
What is the modern replacement for the legacy FB2060 circuit breaker?
Eaton designates the FD2060 as the direct modern replacement for the obsolete FB2060. Depending on your specific interrupting capacity requirements, the FDB2060 or EHD2060 may also serve as suitable F-frame alternatives.
What wire sizes do the terminals on the FB2060 accept?
The factory-installed lugs accept 14 AWG through 1/0 AWG copper or aluminum conductors. When using aluminum wire, applying a suitable joint compound is recommended to prevent terminal overheating.
Is the FB2060 rated for DC voltage applications?
Yes, this breaker carries a 250VDC rating with a 10 kAIC interrupting capacity. It is approved for use in substantially non-inductive DC circuits.
How is the FB2060 installed in a panelboard?
It is a bolt-on molded case circuit breaker that fastens directly to the panelboard bus. Ensure the panel is de-energized before bolting the breaker into place.
What protection functions are included in the FB2060 trip unit?
The breaker uses a fixed thermal-magnetic trip unit providing Long-Time (thermal) and Instantaneous (magnetic) protection, commonly referred to as an LI trip configuration.
How can I test the mechanical operation of the FB2060?
You can use the push-to-trip button on the front of the breaker to manually verify the tripping function and periodically exercise the operating mechanism. After tripping, reset the breaker by moving the handle to the extreme OFF position before turning it back ON.
