Description
Serving as a reliable overcurrent solution, the Square D FAL36100 is a 100A, 3-pole molded case circuit breaker with standard thermal-magnetic (LI) trip functions. Built for unit mount configurations, it installs into Square D enclosures, switchboards, and motor control centers. This legacy F-Frame breaker crosses over to the newer HGL36100 or BDL36100 series for facility upgrades. With an 18kAIC rating at 480VAC, it provides robust fault protection and includes an AL100FA mechanical lug kit.Specifications

Product FAQs
6 answersWhat are the magnetic trip thresholds for the FAL36100?
This 100A thermal magnetic circuit breaker has a factory-fixed magnetic hold current of 900A and a magnetic tripping current of 1700A.
Is the Square D FAL36100 still actively manufactured?
No. Schneider Electric officially discontinued the legacy F-frame series in January 2021, moving it to end-of-commercialization status.
Which modern circuit breaker replaces the Square D FAL36100?
Schneider Electric recommends the PowerPact B-frame series, specifically the BDL36100, as the direct performance equivalent. When upgrading, electricians may need to verify backpan spacing and use B-frame conversion hardware, as the physical dimensions differ from the original F-frame footprint.
What replacement terminal lug kit fits the FAL36100?
This circuit breaker utilizes the AL100FA lug kit for both the line and load sides. The lugs accommodate 14 to 1/0 AWG copper conductors or 12 to 1/0 AWG aluminum conductors.
Will the FAL36100 install into a Square D I-Line panelboard?
No. The FAL36100 is a unit-mount, feed-thru breaker designed to be bolted directly to a mounting pan. It does not feature the plug-on jaw connections required to mount on an I-Line busbar.
How do I lock out the FAL36100 for safe maintenance?
You can use the Square D HPAFK padlock attachment. This accessory mounts directly to the breaker and allows it to be locked in either the ON or OFF position for safe electrical servicing.
