Square D FA / FAL: Replacement & Cross-Reference

The Square D FA and FAL are discontinued F-frame molded-case breakers rated to 100 A. The current path is the PowerPact H-frame (HD / HG / HJ / HL), chosen by interrupting rating. FAL denotes the higher-interrupting version of the FA frame, so match the interrupting rating (AIC), not just the amp rating, when you cross-reference. To keep a panel as-built, Edmundson Industrial sources new-surplus, used-tested, and reconditioned FA and FAL breakers.

Cross-Reference

If you have (obsolete)	Recommended path	Notes
FA (standard AIC)	PowerPact HD / HG by amp & AIC	Match the interrupting rating to the available fault current at the panel.
FAL (higher AIC)	PowerPact HJ / HL	FAL is the high-interrupting version: do not down-rate AIC on the swap.
Keep the panel as-built	New-surplus / used-tested FA or FAL (we source)	True drop-in. Match poles, voltage, amp, and AIC on the full catalog string.
I-Line / plug-on variant	Like-for-like surplus, or PowerPact I-Line + adapter	I-Line footprint changed: our fab side makes adapter and filler hardware.

Cross-references are starting points: confirm interrupting rating, poles, voltage, trip type, and mounting before substituting. Send the catalog number and we'll verify the match.

Replacing an FA on an I-Line panelboard? The PowerPact I-Line footprint differs from the legacy FA stab. Our fabrication side builds adapter and filler hardware so a current breaker lands in the old opening: part and panel on one PO.

Key Specs (frame overview)

F-frame thermal-magnetic molded-case breaker, to 100 A
1, 2, or 3 pole; 240 / 480 / 600 VAC by catalog code
FA vs FAL = interrupting-rating tiers on the same frame
Unit-mount and I-Line plug-on styles
Accessories: shunt trip, auxiliary / alarm switch, undervoltage release, lugs: confirm per catalog

Is the Square D FA / FAL still made?

No. FA and FAL are discontinued; the PowerPact H-frame is the current equivalent. Because FA-class breakers sit in thousands of legacy panelboards, the surplus market for them is deep: FA-frame numbers like FA32100 trade in the thousands of active marketplace listings while barely registering on Google. The practical play is a surplus drop-in now and a PowerPact retrofit at a planned panel upgrade.

FAQ

Is the Square D FA / FAL discontinued?

Yes: the FA and FAL frames are discontinued. New-surplus, used-tested, and reconditioned units remain available through Edmundson Industrial.

What is the difference between FA and FAL?

Same F-frame and amp range; FAL carries a higher interrupting rating (AIC). When cross-referencing, match or exceed the original AIC, not just the amp rating.

What replaces a Square D FA breaker?

The PowerPact H-frame (HD / HG / HJ / HL), selected by amp rating and interrupting rating. We also source original FA / FAL surplus to keep a panel as-built.

Can you source a specific number like FA32100?

Yes: FA32100 is a common catalog number on the surplus market. Send the exact string and we'll quote new-surplus, used-tested, or reconditioned with condition disclosed.

Will a PowerPact H-frame fit my FA panelboard?

Unit-mount usually adapts; I-Line plug-on footprints changed. Our fabrication side makes adapter and filler plates so the current breaker fits the legacy opening.
