Description
Designed for specialized industrial applications, this 20A thermal-magnetic breaker features a factory-installed ground fault shunt trip for use with add-on ground fault modules. It installs into standard Square D enclosures, switchboards, and unit-mount panelboards. While this legacy F-Frame model has been replaced by the PowerPact B-Frame (BGL26020), it remains a critical replacement part. The unit delivers an 18kAIC rating at 480VAC and includes Visi-Trip visual trip indication.Specifications

Product FAQs
6 answersWhat does the G suffix indicate on the FAL24020G catalog number?
The G suffix designates that this breaker includes a factory-installed ground fault shunt trip. This internal mechanism allows an external ground fault sensing module to trip the breaker when a fault is detected in the system.
Which panels and enclosures are compatible with the FAL24020G?
This legacy F-Frame breaker is designed for unit-mount installations in compatible Square D enclosures, switchboards, and unit-mount panelboards.
Can the FAL24020G be installed in an I-Line panelboard?
No, the FAL24020G is a unit-mount breaker with a feed-thru connection type. It requires physical mounting hardware and wire terminations on both the line and load sides, making it incompatible with I-Line plug-on bus systems.
What are the acceptable wire types and sizes for the FAL24020G lugs?
The included feed-thru lugs support both copper and aluminum wiring. Electricians can terminate 14 to 4 AWG copper or 12 to 4 AWG aluminum conductors directly to the breaker terminals.
Are the trip settings adjustable on the FAL24020G?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time thermal overload protection and the instantaneous magnetic short-circuit protection are factory set and cannot be adjusted in the field.
Is the Square D FAL24020G part of a current product line?
The FAL series belongs to the legacy Square D F-Frame family. While it is frequently sourced to maintain or expand older switchboards and enclosures, modern Square D systems typically utilize the PowerPact series.
