Product FAQs
7 answersWhat enclosures or panelboards are compatible with the FAL24050?
It is compatible with individual Square D enclosures, switchboards, and unit-mount panelboards. Because it is a feed-thru breaker, it cannot be installed in I-Line plug-on panels.
What are the standard lugs for the FAL24050?
This breaker typically uses AL100FA lugs on both the line and load sides. These lugs accommodate 14 to 1/0 AWG copper or 12 to 1/0 AWG aluminum wire.
Is the Square D FAL series obsolete?
Yes, the legacy F-Frame series has been discontinued by Schneider Electric. The modern equivalent is the PowerPact B-Frame series, though retrofitting may require specific mounting adapters.
Can the FAL24050 be used in DC applications?
Yes, this thermal-magnetic breaker is rated for up to 250VDC with a 10kA interrupting capacity, making it suitable for ungrounded DC systems.
How is the FAL24050 physically mounted?
This breaker features a unit-mount design. It bolts directly to a mounting pan or chassis and uses wire lugs on both the line and load sides to make electrical connections.
What does the LI trip function indicate on this breaker?
The LI designation means the breaker provides Long-Time thermal protection for overloads and Instantaneous magnetic protection for short circuits. Both trip points are fixed on the FAL24050.
What is the physical frame size of the FAL24050?
The FAL24050 is built on Square D's legacy 100A F-Frame footprint. It uses the same physical dimensions as other F-Frame breakers but is factory-calibrated to a fixed 50A continuous current rating.
