Description
Engineered for demanding commercial environments, the Square D FAL22100-1021 provides robust long-time and instantaneous (LI) overcurrent protection. Designed as a unit-mount device, this legacy F-Frame breaker fits securely into Square D enclosures and switchboards. For modern upgrades, it is replaced by the PowerPacT BDL26100. This 2-pole, 100A breaker features a 10kAIC rating at 240VAC and includes a factory-installed 120-240VAC shunt trip (suffix -1021) for remote tripping capabilities.Specifications

Product FAQs
6 answersWhat does the -1021 suffix indicate on the FAL22100-1021 catalog number?
The -1021 suffix designates a factory-installed 120-240VAC shunt trip accessory. This allows the breaker to be opened remotely via an external control signal, which is commonly used for emergency stops or automated safety shutdowns.
How does the FAL22100-1021 mount inside a panel?
This is a unit-mount, feed-thru circuit breaker. Unlike plug-on or I-Line breakers that connect directly to a busbar, it requires physical mounting hardware and uses wire lugs on both the line and load sides. It is compatible with standard Square D enclosures, control panels, and switchboards designed for legacy F-frame breakers.
What are the acceptable wire sizes for the FAL22100-1021 terminals?
The factory lugs accommodate 14 AWG to 1/0 AWG copper conductors, or 12 AWG to 1/0 AWG aluminum conductors. Ensure proper torque specifications are followed during installation to maintain a secure connection.
Are the trip settings adjustable on the FAL22100-1021?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time (thermal) and instantaneous (magnetic) trip functions are factory-set and cannot be adjusted in the field.
Is the Square D FAL F-frame series still in active production?
The FAL series is a legacy product line that has been largely replaced by the newer Schneider Electric PowerPact series. When replacing an FAL22100-1021 with a modern PowerPact equivalent, verify that the new breaker dimensions and mounting hardware are compatible with your existing enclosure, and ensure a compatible shunt trip accessory is included.
Can this breaker be used for DC voltage applications?
Yes, the FAL22100-1021 is rated for use on DC systems up to 250VDC, where it provides an interrupting rating of 5 kAIC. This makes it suitable for specific industrial control or battery backup circuits requiring a 100A disconnect.
