Designed to support heavy commercial loads, this 100A molded case circuit breaker utilizes fixed thermal and magnetic trip elements for reliable LI protection. The breaker integrates into existing Square D panelboards and switchboards via unit mounting, avoiding the need for complex retrofits. Equipped with the signature Visi-Trip indicator, maintenance personnel can quickly spot tripped circuits. For modern replacements, Schneider Electric recommends the PowerPact HDL26100 as the successor.
Is the Square D FAL22100 obsolete, and what is the modern replacement?
The FAL22100 is a legacy F-Frame circuit breaker. For new installations and retrofits, Schneider Electric has designated the PowerPact B-Frame series as the modern replacement for 15A to 125A F-Frame applications.
Can the FAL22100 be installed in an I-Line panelboard?
No. The FAL22100 is a unit-mount, feed-thru circuit breaker that uses lug connections on both the line and load sides. It lacks the plug-on jaw required for I-Line distribution panels. For I-Line applications, an FA, FH, or FC frame breaker is required.
What lug kit is used on the FAL22100, and what are the conductor limits?
This 100A breaker typically utilizes the AL100FA lug kit. These lugs accept 14 to 1/0 AWG copper (Cu) or 12 to 1/0 AWG aluminum (Al) conductors.
Does the FAL22100 support DC voltage applications?
Yes, in addition to its 240VAC rating, this thermal-magnetic breaker is rated for 250VDC systems with an interrupting capacity of 5kAIC.
What protection does the fixed LI trip unit provide?
The LI designation means the thermal-magnetic trip unit delivers Long-Time (L) thermal protection for standard overloads and Instantaneous (I) magnetic protection for short circuits. Both trip thresholds are fixed and cannot be field-adjusted.
