Designed to protect industrial circuits, the Square D FCP34060 is a 60A molded case circuit breaker. It offers robust long-time and instantaneous trip functions for reliable power distribution. The device integrates into legacy Square D enclosures via a standard bolt-on configuration. When replacing older F-Frame units, the modern HJL36060 serves as the exact manufacturer substitute. With an extra-high interrupting capacity of 65kAIC at 480VAC, it is fully HACR rated.
What equipment is the FCP34060 circuit breaker designed to fit?
This legacy F-frame breaker is compatible with older Square D panelboards, switchboards, and motor control centers that accept bolt-on feed-thru breakers.
What is the modern replacement for the legacy FCP34060 breaker?
When replacing older F-frame units, the modern Square D PowerPact H-frame HJL36060 serves as the exact manufacturer substitute.
Does the FCP34060 connect directly to a busbar?
No, this is a feed-thru circuit breaker. It uses lug terminals on both the line and load sides for hardwired connections rather than plugging directly onto a busbar.
What wire sizes and materials are compatible with the FCP34060 terminals?
The included line and load side lugs accept 14 AWG to 1/0 AWG wire and are rated for both copper (Cu) and aluminum (Al) conductors.
Is the FCP34060 suitable for HVAC applications?
Yes, this breaker is fully HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment.
What is the frame size of the FCP34060?
It is built on the Square D 100A F-frame chassis, though this specific model is factory-calibrated for a 60A continuous current rating.
