Product FAQs
5 answersIs the Square D FAL14100 circuit breaker obsolete?
Yes, the Square D F-Frame series is a legacy product line. The FAL14100 has been superseded by the newer PowerPact B-Frame series, such as the BDL16100. However, using an original F-Frame replacement can often prevent the need for costly panel retrofits.

Are the trip settings on the FAL14100 adjustable?
No, this breaker features fixed thermal and fixed magnetic trip settings. It provides standard long-time and instantaneous (LI) overcurrent protection without field adjustability.
Can the FAL14100 be used in DC electrical systems?
Yes, in addition to its standard AC ratings, this breaker is rated for 125VDC with a 10kAIC interrupting capacity, allowing it to be used in compatible direct current applications.

The standard lugs accommodate 14 to 1/0 AWG copper (Cu) conductors or 12 to 1/0 AWG aluminum (Al) conductors.
