Product FAQs
8 answersWhat does the 1021 suffix mean in the FAL340201021 catalog number?
The 1021 suffix indicates that this circuit breaker includes a factory-installed 120-240VAC shunt trip. This allows the breaker to be opened remotely via a control signal for enhanced safety and facility control.
What is the modern replacement for the legacy Square D FAL340201021?
The legacy F-Frame series has been superseded by the Square D PowerPact B-Frame and H-Frame series. To match the exact functionality of the FAL340201021, you will need a 20A, 3-pole PowerPact breaker, such as the HDL34020 or BDL34020, equipped with a compatible 120-240VAC shunt trip accessory.
What type of enclosures or panels is the FAL340201021 compatible with?
This unit-mount molded case circuit breaker is designed for hardwired installation in standard Square D enclosures, switchboards, and motor control centers. It features a feed-thru connection and is not compatible with I-Line plug-on panelboards.
Can I adjust the trip settings on the FAL340201021?
No, this breaker features fixed thermal and fixed magnetic trip elements. It provides standard long-time and instantaneous (LI) protection that cannot be field-adjusted.
What wire sizes are accepted by the lugs on this 20A breaker?
The included line and load lugs accept 14 to 4 AWG copper wire or 12 to 4 AWG aluminum wire.
Can the FAL340201021 be used in DC power systems?
Yes, in addition to its AC ratings, this breaker is rated for 250VDC applications with an interrupting capacity of 10 kAIC.
How is the shunt trip wired on the FAL340201021?
The factory-installed 120-240VAC shunt trip features its own control wiring leads exiting the breaker housing. These leads must be wired to a remote normally open contact and a compatible 120V or 240V AC control power source to actuate the trip mechanism.
Does this breaker include a visual trip indicator?
Yes, Square D F-Frame breakers feature a Visi-Trip indicator. This provides a clear visual confirmation when the breaker has tripped due to an overcurrent event, a short circuit, or actuation by the shunt trip.
