Product FAQs
7 answersWhat equipment is compatible with the FAL14015 circuit breaker?
This unit mount breaker is designed for installation in Square D enclosures, switchboards, and unit mount panelboards. Because it is a unit mount device, it cannot be installed in I-Line panelboards, which require plug-on connections.
Is the Square D FAL14015 still in active production?
The FAL14015 is part of the legacy F-frame molded case circuit breaker family. Schneider Electric has designated the PowerPact B-frame series as the modern replacement for legacy F-frame applications.
Can the FAL14015 be used in DC voltage applications?
Yes, in addition to its primary AC rating, this breaker is rated for use on direct current systems. It provides a maximum interrupting capacity of 10kA at 125VDC.
What wire gauge and material can be used with the FAL14015 terminals?
The standard feed-thru lugs accept wire sizes from 14 AWG to 4 AWG. The terminals are dual-rated for both copper (Cu) and aluminum (Al) conductors.
Are the trip settings on the FAL14015 adjustable?
No, this breaker utilizes a thermal magnetic trip unit with fixed thermal and fixed magnetic settings. It provides standard long-time and instantaneous (LI) trip functions without field adjustability.
How is the FAL14015 mounted?
It is a unit mount, feed-thru circuit breaker. It must be bolted or fastened directly to the enclosure backpan or mounting surface, rather than plugging onto a distribution busbar.
What does the LI trip function code mean on the FAL14015?
The LI designation indicates that the breaker provides Long-Time (L) and Instantaneous (I) protection. Long-Time protects against sustained overloads, while Instantaneous trips immediately during a short circuit fault.
