Product FAQs
6 answersWill the FAL34035 fit in an I-Line panelboard?
No. The FAL34035 is a unit-mount, feed-thru circuit breaker designed for standard Square D enclosures, switchboards, and unit-mount panelboards. It does not have the plug-on jaw brackets required for I-Line distribution panels.
What is the modern replacement for the discontinued FAL34035?
The legacy Square D F-frame series has been discontinued. For new installations or panel upgrades, Schneider Electric recommends crossing this over to the modern PowerPact B-Frame or H-Frame series. Verify panel mounting requirements before substituting.
Is this breaker HACR rated for HVAC applications?
Yes. As a UL 489 listed molded case circuit breaker, the FAL34035 is HACR rated by default. It is approved for use with heating, air conditioning, and refrigeration equipment that requires group motor protection.
Is the FAL34035 rated for direct current (DC) applications?
Yes, this breaker is rated for 250VDC applications with a 10kA interrupting capacity. This makes it suitable for industrial DC control panels, battery systems, and specific solar applications.
Can the FAL34035 be backfed in a panelboard?
Yes. Because it features a fixed thermal-magnetic trip unit without electronic directional monitoring, it can be safely reverse fed. When used as a backfed main, the National Electrical Code (NEC) requires proper labeling and mechanical hold-down kits.
Do the standard lugs on the FAL34035 accept aluminum wire?
Yes, the factory-installed line and load lugs are dual-rated for both copper and aluminum conductors. They accept copper wire from 14 to 1/0 AWG and aluminum wire from 12 to 1/0 AWG.
