Product FAQs
7 answersCan the FAL34080 be installed in a Square D I-Line panelboard?
No. The FAL34080 is a unit-mount breaker that uses feed-thru lug connections. I-Line panelboards require breakers equipped with specialized plug-on jaw connections.
What wire sizes are compatible with the lugs on this breaker?
The breaker includes dual-rated AL100FA lugs that accept either copper or aluminum conductors. Compatible wire ranges are 14 AWG to 1/0 AWG for copper, and 12 AWG to 1/0 AWG for aluminum.
Is the FAL34080 approved for use in DC electrical systems?
Yes. In addition to its AC ratings, this molded case breaker is rated for up to 250VDC with a 10kA interrupting capacity, allowing it to protect compatible direct current circuits.
What does the LI designation mean for this breaker's trip unit?
LI indicates Long-Time and Instantaneous trip functions. The thermal-magnetic mechanism provides a delayed trip for standard overloads (Long-Time) and an immediate trip response during a short circuit (Instantaneous).
Is the FAL34080 a current production breaker?
No. The Square D FAL series is a legacy F-Frame product that has been discontinued by Schneider Electric. It is primarily sourced today to maintain and repair existing older switchboards and control panels.
What modern circuit breaker replaces the legacy FAL34080?
Schneider Electric typically replaces legacy 80A F-Frame breakers with newer PowerPact B-Frame or H-Frame models, such as the HDL36080. Retrofitting may require specialized mounting hardware or panel modifications.
Can I use this breaker to protect heating and air conditioning loads?
Yes. The FAL34080 is HACR rated, which means it is safety certified to handle the high inrush currents typical of heating, air conditioning, and refrigeration motor loads.
