Product FAQs
5 answersWhat does the "1021" suffix mean on the FAL221001021 circuit breaker?
The "1021" suffix indicates that this breaker includes a factory-installed 120/240VAC shunt trip. If your application does not require a shunt trip, the standard base breaker is the FAL22100.
What types of panels is the FAL221001021 compatible with?
This F-frame breaker is designed for use in Square D enclosures, control panels, and switchboards that accept unit-mount circuit breakers. It is not compatible with I-Line panelboards, which require plug-on connections.
How is the FAL221001021 mounted compared to other Square D F-frame breakers?
The FAL221001021 is a unit-mount (feed-thru) breaker, meaning it bolts directly to a backpan or mounting plate and uses lugs on both the line and load sides. This differs from FA-prefix breakers, which are typically I-Line plug-on breakers.
Can the FAL221001021 be used in DC control circuits?
Yes, in addition to its 240VAC rating, this breaker is rated for up to 250VDC with a 5kAIC interrupting capacity, making it suitable for DC control panels and battery systems.
Does the FAL221001021 require a separate power source for the shunt trip?
Yes, the factory-installed 1021 shunt trip requires an external 120/240VAC control voltage source to actuate the trip mechanism remotely.
