Part of the legacy F-frame series, this 100A, three-pole molded case circuit breaker delivers robust thermal-magnetic protection. It serves commercial facilities requiring dependable power distribution. The unit mount design allows secure installation into compatible Square D enclosures and switchboards. For modern upgrades, this is replaced by the BDL36100. Featuring a 10kA interrupting rating at 240VAC, it includes a Visi-Trip indicator for rapid fault identification.

Product FAQs

6 answers
Is the FAL32100 circuit breaker obsolete?

Yes, Schneider Electric officially discontinued the legacy Square D F-frame series in 2021. The manufacturer recommends the PowerPact BDL36100 as a modern replacement. However, installing a B-frame breaker in an older enclosure often requires mounting adapters, which is why many panel builders prefer to source an exact legacy drop-in.

Can the FAL32100 be reverse fed?

Yes. Because it is a thermal-magnetic breaker and does not feature directional line and load markings, it is suitable for reverse-feed configurations in generator backfeed or alternative supply applications.

What enclosures are compatible with this F-frame breaker?

This is a unit-mount breaker equipped with lugs on both ends, designed for standard backpan mounting in legacy Square D control panels, individual enclosures, and switchboards. It will not fit in I-Line busway panels, which require plug-on jaw connections.

What does the 10kAIC at 240VAC rating mean for my installation?

The 10,000 Ampere Interrupting Capacity (AIC) is the maximum fault current the breaker can safely clear at 240V AC. While adequate for many light commercial branch circuits, you must verify that the available fault current at your panel does not exceed 10kA.

Is this breaker rated for direct current (DC) circuits?

Yes, the FAL32100 carries a dedicated 250VDC rating with a 5kAIC interrupting capacity. This allows it to protect industrial DC control circuits and specific battery applications, which AC-only breakers cannot safely interrupt.

What are the lug torque requirements for the FAL32100?

The standard AL100FA mechanical lugs accept 14 to 1/0 AWG copper or aluminum wire. Field wiring requires approximately 50 lb-in (5.6 N.m) of torque, but electricians must always verify the exact specification printed on the breaker faceplate before finalizing terminations.
