Product FAQs
6 answersWhat does the -1021 suffix indicate on the FAL34030-1021?
The -1021 suffix designates a factory-installed 120/240VAC shunt trip. This internal accessory allows the breaker to be tripped remotely using an external voltage signal.
Can I install the FAL34030-1021 in a Square D I-Line panelboard?
No. This is a unit-mount breaker designed to be hardwired into standard enclosures, switchboards, and motor control centers. It lacks the plug-on jaw connections required for I-Line distribution panels.
What is the modern replacement for the legacy FAL34030-1021?
The FAL series is a legacy F-Frame breaker. For modern panel upgrades, it is typically replaced by the PowerPact H-Frame HDL34030. If you migrate to the PowerPact series, you will need to add a compatible shunt trip accessory to replicate the -1021 functionality.
Are the line and load lugs included with this breaker?
Yes, this feed-thru breaker comes standard with lugs on both the line and load sides. The terminals accept 14 to 4 AWG copper or 12 to 4 AWG aluminum conductors.
Are the thermal and magnetic trip settings adjustable on this breaker?
No, the FAL34030-1021 features fixed thermal and fixed magnetic trip settings. The long-time and instantaneous trip points cannot be modified in the field.
Does the FAL34030-1021 provide ground fault equipment protection?
No. This breaker features standard thermal-magnetic trip units with long-time and instantaneous (LI) functions for overload and short-circuit protection. It does not provide ground fault or arc fault protection.
