Operating at up to 480VAC, the Square D FAL34100-2100 is a 3-pole, 100A molded case circuit breaker. It utilizes fixed thermal and magnetic trip units to protect industrial circuits. The unit mount configuration allows for straightforward installation into Square D enclosures and control panels. As a legacy F-Frame device, it is superseded by the HDL36100. A key feature of this model is the integrated bell alarm, which alerts operators when the breaker trips due to an overcurrent event.

Product FAQs
6 answers
What does the -2100 suffix mean on the Square D FAL34100-2100?
The -2100 suffix indicates that this circuit breaker includes a factory-installed bell alarm. This contact alarm activates when the breaker trips due to an overcurrent event, allowing for remote fault indication.
What is the modern replacement for the legacy FAL34100-2100?
The FAL series is a legacy F-Frame molded case circuit breaker. Schneider Electric designates the PowerPact B-Frame series as the direct replacement for legacy F-Frame applications, though retrofitting may require mounting adaptations.
How is the FAL34100-2100 mounted in a panel?
This is a unit mount, feed-thru circuit breaker. It bolts directly to a backpan or mounting surface and uses wire lugs for both line and load connections, making it suitable for standalone enclosures or panels without an I-Line busbar.
What wire sizes are accepted by the lugs on the FAL34100-2100?
The factory-installed lugs accept 14 to 1/0 AWG copper wire or 12 to 1/0 AWG aluminum wire. Ensure proper torque specifications are followed during installation to maintain a secure electrical connection.
Are the trip settings adjustable on the FAL34100-2100?
No, this breaker features a thermal-magnetic trip unit with fixed thermal (long-time) and fixed magnetic (instantaneous) trip settings. It does not support field adjustments for the trip curve.
What types of equipment is the FAL34100-2100 compatible with?
This F-Frame circuit breaker is designed for unit mount installations and is compatible with standard Square D enclosures, switchboards, and industrial control panels that accommodate legacy F-Frame dimensions.
