The 1021 suffix signifies that this breaker includes a factory-installed 120/240VAC shunt trip. This accessory allows for remote tripping of the breaker for added safety or control.

How does the Square D FAL240301021 mount into an electrical system?

This is a unit-mount, feed-thru circuit breaker. It does not plug or bolt directly onto a panelboard bus. Instead, it mounts independently and uses wire lugs on both the line and load sides.

This unit-mount breaker is designed for use in compatible Square D enclosures, switchboards, and unit-mount panelboards that accommodate legacy F-frame molded case circuit breakers.

What is the modern replacement series for the discontinued Square D FAL breakers?

For modern retrofits, Square D F-frame breakers are typically replaced by the newer PowerPacT B-Frame molded case circuit breakers. When crossing this specific part, ensure the replacement also includes a 120/240VAC shunt trip to match the original functionality.

What are the wire size and material requirements for installing the FAL240301021?

Yes, in addition to its AC ratings, this breaker is rated for up to 250VDC with a 10kA interrupting capacity for use in direct current applications.
