Product FAQs
7 answersIs the Square D FAL14030 still manufactured or has it been replaced?
The FAL14030 is part of the legacy F-Frame series. While it remains essential for maintaining existing infrastructure, Schneider Electric has succeeded this series with the PowerPact B-Frame. The BDL16030 is the modern equivalent for 1-pole 30A applications.
What types of equipment are compatible with the FAL14030?
This unit-mount breaker is designed for installation in standard Square D enclosures, industrial control panels, and older switchboards configured for legacy F-Frame breakers. It utilizes a feed-thru connection rather than an I-Line plug-on connection.
What does the LI trip function on the FAL14030 indicate?
The LI designation means the breaker is equipped with a thermal-magnetic trip unit providing fixed Long-Time (L) protection against overloads and fixed Instantaneous (I) protection against short circuits.
What are the physical dimensions of the FAL14030 breaker?
The FAL14030 measures approximately 6.4 inches high, 1.5 inches wide, and 4.13 inches deep. The 1.5-inch width is standard for legacy Square D F-Frame single-pole breakers.
Can the FAL14030 be used in direct current applications?
Yes. In addition to its primary 277VAC rating, this breaker is certified for use in DC systems up to 125VDC, where it provides an interrupting capacity of 10kA.
What wire sizes are accepted by the lugs on the FAL14030?
The factory-installed feed-thru lugs accommodate both copper and aluminum conductors. You can use 14 to 4 AWG for copper wiring or 12 to 4 AWG for aluminum wiring.
Does the FAL14030 provide GFCI or AFCI protection?
No. The FAL14030 is a standard thermal-magnetic breaker and does not include ground fault or arc fault protection circuitry.
