Description
Built for complex control schemes, this 20A, 3-pole molded case circuit breaker includes a factory-installed 120-240VAC shunt trip. This specific configuration allows facility managers to remotely open the breaker for emergency shutdowns or automated processes. The unit mounts into Square D enclosures, switchboards, and motor control centers. While it is a legacy F-Frame component, it remains essential for maintaining existing infrastructure before upgrading to the HGL36020SA.Specifications

Product FAQs
6 answersWhat does the 1021 suffix mean on the FAL360201021 catalog number?
The 1021 suffix indicates that this breaker includes a factory-installed 120/240VAC shunt trip accessory. This allows the breaker to be tripped remotely via a separate control circuit.
Can I use the FAL360201021 to replace a standard FAL36020?
You can physically mount it in the same space, but the FAL360201021 is specifically designed for applications requiring a remote shunt trip. If your system does not use a 120VAC or 240VAC control circuit for remote tripping, the standard FAL36020 is the correct replacement.
What equipment is compatible with this F-frame circuit breaker?
As a unit-mount, feed-thru breaker, the FAL360201021 is designed for installation in Square D enclosures, switchboards, and motor control centers. It is not compatible with I-Line panelboards, which require FA series breakers with plug-on brackets.
How is the shunt trip wired and operated?
The internal shunt trip coil requires a momentary application of 120VAC or 240VAC from an external control circuit. When the control circuit energizes the coil, it mechanically forces the breaker to trip and open the contacts.
How should I wire the FAL360201021 for a 20A circuit?
The factory lugs accept 14 to 4 AWG copper or 12 to 4 AWG aluminum conductors. Electricians must ensure the selected wire gauge meets local codes for a 20A load and that the lugs are properly torqued to maintain a secure connection.
How does the thermal-magnetic trip unit protect the electrical system?
The breaker features fixed Long-Time and Instantaneous (LI) trip functions. The thermal component protects against sustained overloads by heating a bimetallic strip to trip the breaker, while the magnetic component provides immediate tripping when it detects a severe short circuit.
