Description
The Square D FAL320401021 is a 3-pole, 40A MCCB designed for industrial environments. The 1021 suffix denotes a factory-installed 120-240VAC shunt trip, enabling remote shutdown capabilities. This F-Frame breaker utilizes a unit mount configuration for Square D enclosures and switchboards. The PowerPact B-Frame (BDL36040) is the modern replacement. With a 10 kAIC rating at 240VAC, it relies on fixed thermal-magnetic elements for LI protection and features a highly visible Visi-Trip indicator.Specifications

Product FAQs
5 answersWhat does the "1021" suffix mean on the Square D FAL320401021?
The 1021 suffix indicates that this circuit breaker includes a factory-installed 120-240VAC shunt trip. This accessory allows the breaker to be tripped remotely by applying a voltage signal, which is often required for emergency shutdown or fire alarm integration.
What is the modern replacement for the legacy FAL320401021 circuit breaker?
The Square D F-Frame is a legacy series. For new installations or modern replacements, Schneider Electric recommends the PowerPact B-Frame series, specifically the BDL36040. To match the functionality of the 1021 suffix, you will also need to add a compatible field-installable shunt trip accessory to the B-Frame breaker.
Can I adjust the trip settings on the FAL320401021?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The Long-Time (L) and Instantaneous (I) protection settings are factory-calibrated and cannot be adjusted in the field.
Is the FAL320401021 a plug-on or bolt-on breaker?
Neither. The FAL320401021 is a unit-mount circuit breaker with a feed-thru connection. It is designed to be hardwired using the included line and load lugs, and is typically installed in Square D control panels, switchboards, or standalone enclosures rather than plugging directly onto a panelboard bus.
How can I manually test the tripping mechanism on the FAL320401021?
This F-Frame breaker features a built-in push-to-trip button. Pressing this button allows you to manually trip the breaker for testing and maintenance without exposing yourself to live internal components.
