Product FAQs
7 answersWhat does the "-1127" suffix mean on the FAL32070-1127?
The "-1127" suffix indicates that this breaker includes a factory-installed 24Vdc Undervoltage Release (UVR). This accessory automatically trips the breaker if the control voltage drops below a predetermined safety threshold.
Is the FAL32070-1127 compatible with I-Line panelboards?
No, this is a unit mount (feed-thru) breaker designed to be bolted into place and wired with mechanical lugs on both the line and load sides. For I-Line panelboards that require a plug-on line connection, you will need the FA32070 equivalent.
What is the current replacement for the legacy Square D FAL series?
The FAL series is a legacy F-frame breaker that has been superseded by the Square D PowerPact B-frame series. For new installations or complete panel upgrades, PowerPact B-frame breakers provide the modern equivalent for 15A to 125A unit mount applications.
Are the thermal and magnetic trip points adjustable on this breaker?
No, the FAL32070-1127 features a fixed thermal-magnetic trip unit. The long-time overload and instantaneous short-circuit protection settings are factory-calibrated and cannot be modified in the field.
Can I use aluminum wire with the factory lugs on this breaker?
Yes, the standard mechanical lugs on the FAL32070-1127 are dual-rated for both copper and aluminum conductors. They accept 14 to 1/0 AWG copper wire and 12 to 1/0 AWG aluminum wire.
Does this breaker support direct current (DC) applications?
Yes, in addition to its standard AC ratings, this breaker is certified for DC systems up to 250VDC. When deployed in a 250VDC application, it provides a 5kA interrupting capacity.
What frame size does the FAL32070-1127 belong to?
This breaker is part of the Square D legacy F-frame family. It shares the same physical footprint as other FA, FH, and FC breakers, but is specifically configured for unit mounting rather than I-Line bus connections.
