Description
Operating as a core component in commercial power distribution, the Square D FAL24020 offers reliable 20-amp overcurrent protection. It utilizes fixed thermal and magnetic trip elements to safeguard circuits. This unit-mount breaker fastens into legacy Square D enclosures using the provided line and load lugs. For modernizations, Schneider Electric recommends the PowerPact B-Frame BDL26020 as a replacement. Certified for HACR applications, it delivers an 18kA interrupt capacity at 480VAC.Specifications

Product FAQs
5 answersWhat is the modern replacement for the legacy FAL24020?
The FAL frame is a legacy Square D product. Schneider Electric recommends the PowerPact B-Frame, specifically catalog number BDL26020, as the direct replacement for 20A, 2-pole, 480VAC applications.
Can the FAL24020 be reverse fed?
Yes. Square D thermal-magnetic breakers in the FAL series do not have specific Line and Load markings, meaning they can be safely reverse fed for supply-side applications.
What are the torque specifications for the standard AL50FA lugs?
The standard AL50FA lugs require 35 lb-in of torque for 14-4 AWG copper and 12-4 AWG stranded aluminum wire. For 12-10 AWG solid aluminum wire, the torque requirement is 15 lb-in.
Can the FAL24020 be used in direct current (DC) circuits?
Yes. In addition to its standard AC ratings, this breaker is certified for use in DC circuits up to 250VDC, making it suitable for industrial DC control panels and switchboards.
How does a unit-mount FAL breaker install into an enclosure?
As a feed-thru unit-mount breaker, it fastens directly to the backpan of legacy Square D enclosures or control panels using mounting screws. It does not plug or bolt onto a panelboard busbar.
