Product FAQs
7 answersWhat is the difference between the FAL24100 and the FA24100?
The FAL24100 is a unit-mount, feed-thru breaker designed to bolt onto a backpan using lugs. The FA24100 is the I-Line plug-on version of the same 100A F-frame breaker, designed specifically for Square D I-Line panelboards and switchboards.
What is the modern replacement for the obsolete FAL24100?
The legacy F-frame series has been discontinued by Schneider Electric. For new installations or system upgrades, the PowerPact B-frame series is the designated modern replacement. Exact catalog numbers will depend on your specific voltage and interrupting capacity requirements.
What replacement lug kit is compatible with the FAL24100?
The standard mechanical lug kit for 100A F-frame breakers is the AL100FA. It accepts 14 to 1/0 AWG copper wire or 12 to 1/0 AWG aluminum wire.
Are the thermal-magnetic trip settings on the FAL24100 adjustable?
No, the FAL24100 features a fixed thermal-magnetic trip unit. Both the Long-Time thermal overload and Instantaneous magnetic short-circuit trip functions are factory-set and cannot be adjusted in the field.
Can the FAL24100 be used in DC circuits?
Yes, this breaker is rated for up to 250VDC with a 10kA interrupting capacity, making it suitable for both AC and DC applications.
Can I install the FAL24100 in an I-Line panelboard?
No. The FAL24100 is a unit-mount breaker that requires a bolt-on backpan installation. For I-Line panelboards, you must use a plug-on I-Line breaker such as the FA24100 or its modern PowerPact equivalent.
Is the FAL24100 suitable for HVAC applications?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment motor loads.
