Description
Designed for maximum system reliability, this 60-amp molded case breaker provides essential current-limiting capabilities. It effectively restricts peak let-through currents during major fault events in industrial settings. The breaker installs into legacy Square D switchboards and features a two-pole configuration housed within a three-pole frame. For complete system upgrades, it is officially replaced by the PowerPact HJL26060. A trip-free mechanism ensures the contacts open safely under load.Specifications

Product FAQs
8 answersWhat equipment is compatible with the FCL24060 circuit breaker?
This unit mount breaker is designed for installation in standard Square D enclosures, switchboards, and motor control centers. It is not designed for I-Line panelboards.
What wire sizes and materials are accepted by the terminals on this breaker?
The line and load side lugs accommodate 14 to 1/0 AWG copper (Cu) conductors or 12 to 1/0 AWG aluminum (Al) conductors.
How is the FCL24060 mounted within an enclosure?
It features a feed-thru, unit mount design. It must be bolted or fastened directly to the backpan or mounting surface rather than plugging onto a busbar.
What does the current limiting feature of the FCL frame provide?
Current limiting breakers restrict the peak let-through current and energy during a severe fault. This rapid clearing action helps protect downstream electrical equipment from excessive thermal and magnetic stress.
Is the FCL24060 a current production model or a legacy frame?
The FCL series is a legacy F-frame molded case circuit breaker. For modern installations and upgrades, it has generally been superseded by the Square D PowerPact H-frame series.
How does the thermal magnetic trip unit function on this breaker?
The trip unit provides fixed thermal protection for long-time overloads and fixed magnetic protection for instantaneous short-circuit events. The settings are factory calibrated and cannot be adjusted in the field.
What are the primary safety requirements when replacing an FCL frame breaker?
Installation must be performed by a licensed electrician. The switchboard or motor control center must be completely de-energized, locked out, and verified with a properly rated voltage tester before removing the existing breaker or terminating conductors.
Can this 2-pole breaker be utilized in a 3-phase switchboard?
Yes, it can be installed in a 3-phase system provided the mounting hardware is compatible, but it will only connect to two phases to supply single-phase loads.
