Description
Built for advanced control, the Square D FAL360801021 integrates a 120-240VAC shunt trip for remote power disconnection. This 3-pole, 80-amp molded case circuit breaker utilizes thermal-magnetic technology for reliable long-time and instantaneous (LI) protection. The unit mount configuration is designed for Square D enclosures and panelboards. As a legacy F-Frame device, it crosses over to the PowerPact HDL36080. It delivers an 18kAIC rating at 480VAC and features a Visi-Trip indicator.Specifications

Product FAQs
7 answersWhat does the 1021 suffix indicate on the FAL360801021?
The 1021 suffix means this breaker includes a factory-installed 120/240VAC shunt trip. This allows the breaker to be opened remotely by applying a control voltage to the shunt trip terminals.
Is the FAL360801021 compatible with I-Line panelboards?
No. The FAL360801021 is a unit-mount (feed-thru) circuit breaker. It is designed for standard Square D enclosures, switchboards, and panelboards that accept lug-in/lug-out connections, not plug-on I-Line panels.
How is the shunt trip wired on the FAL360801021?
The internal shunt trip features its own control terminals. When a 120VAC or 240VAC signal is applied to these terminals from a remote switch or relay, it activates the internal solenoid to mechanically trip the breaker.
Can I remove or replace the shunt trip in the FAL360801021?
No. The 1021 suffix indicates a factory-installed shunt trip. It is internally mounted and calibrated at the factory, and cannot be removed or swapped in the field without voiding the UL listing.
Are the thermal and magnetic trip thresholds adjustable on the FAL360801021?
No. This breaker features a fixed thermal-magnetic trip unit. Both the long-time overload protection and the instantaneous short-circuit protection are factory-set and cannot be adjusted in the field.
Is the FAL360801021 rated for direct current (DC) systems?
Yes. While commonly used in 480V and 600V AC systems, this breaker is also UL listed for DC applications up to 250VDC, providing a 10kA interrupting capacity for DC control or battery circuits.
What frame size is the FAL360801021?
It is part of the Square D legacy F-Frame family. The FAL designation specifically identifies it as a standard interrupting, unit-mount breaker within the F-Frame series.
