Product FAQs
7 answersWhat does the 1021 suffix indicate on the FAL340901021?
The 1021 suffix means this breaker includes a factory-installed 120/240VAC shunt trip. This accessory allows automated systems or operators to remotely open the circuit for emergency shutdowns.
How does the shunt trip function improve safety in the FAL340901021?
The integrated 120/240VAC shunt trip allows the breaker to be wired to emergency stop buttons, fire alarm relays, or other safety interlocks. When voltage is applied to the shunt trip coil, it immediately forces the breaker to open and disconnect power.
What is the modern replacement for the discontinued FAL340901021?
The legacy F-Frame series has been replaced by the Square D PowerPact H-Frame series. A modern equivalent is the HDL36090 or HGL36090, which would require a separate field-installable shunt trip accessory to match the 1021 functionality.
Can I use the FAL340901021 if my system does not require a shunt trip?
Yes. This breaker shares the exact physical dimensions and core thermal-magnetic protection as the standard FAL34090. If the shunt trip coil is left unwired, it will operate normally as a standard circuit breaker.
What type of wire is compatible with the terminals on this breaker?
The factory lugs accommodate both copper and aluminum conductors. They accept 14 AWG to 1/0 AWG for copper wire and 12 AWG to 1/0 AWG for aluminum wire.
Where is this unit-mount breaker typically installed?
As a feed-thru, unit-mount breaker, it is designed to be bolted directly to a backpan. It is commonly installed in Square D individual enclosures, switchboards, and motor control centers rather than plug-on or I-Line panelboards.
Are the trip settings adjustable on the FAL340901021?
No, this breaker features a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous protection without adjustable dials.
