Product FAQs
7 answersWhat does the 1380 suffix mean on the FAL360401380?
The 1380 suffix indicates that this breaker includes a factory-installed 120VAC shunt trip and a 1A/1B auxiliary switch for remote tripping and status signaling.
Can I install the FAL360401380 in a Square D I-Line panelboard?
No, this is a unit mount breaker designed for feed-thru lug connections. It lacks the plug-on jaws required for I-Line panelboards and must be installed in standard enclosures or unit mount panels.
What is the modern replacement for the legacy FAL360401380?
The legacy F-Frame FAL series is typically replaced by the modern PowerPact B-Frame series, such as the BDL36040. You will need to ensure the replacement is configured with the equivalent 120VAC shunt trip and auxiliary switch accessories.
How does the shunt trip operate on this breaker?
The factory-installed shunt trip requires a 120VAC external control signal. When voltage is applied to the shunt trip coil, it mechanically trips the breaker to open the circuit, which is commonly used for emergency stops or remote disconnects.
What is the function of the 1A/1B auxiliary switch?
The 1A/1B auxiliary switch provides one normally open and one normally closed contact. These contacts change state when the breaker trips or is manually turned off, allowing you to wire remote status indicators, alarms, or interlocks.
Can I field-install a different shunt trip voltage on this breaker?
The 1380 suffix denotes that the 120VAC shunt trip and auxiliary switch are factory-installed. Field modification of internal accessories on legacy F-Frame breakers is generally not supported and can void the UL listing.
Is the FAL360401380 a current-limiting circuit breaker?
No, the legacy Square D F-Frame FAL series provides standard thermal-magnetic protection. It is not classified as a current-limiting breaker.
