Engineered for advanced monitoring, the Square D FAL360301212 is a 3-pole, 30A molded case circuit breaker. It features a factory-installed 1A/1B auxiliary switch (-1212 suffix), allowing it to interface with external control circuits. This unit-mount F-Frame breaker fits into Square D control panels and switchboards. For modern replacements, the HGL36030 is recommended, requiring a separate auxiliary switch. Rated 25kAIC at 240VAC, it delivers robust thermal-magnetic protection and Visi-Trip.

Product FAQs
6 answers
What does the 1212 suffix indicate on this specific catalog number?
The 1212 suffix designates that the breaker includes a factory-installed 1A/1B auxiliary switch. This provides one normally open and one normally closed contact for remote status signaling or control circuit integration.
How is a unit-mount, feed-thru breaker like this installed?
Unlike plug-on or bolt-on panelboard breakers, this unit-mount breaker is secured independently to a backpan or enclosure using mounting screws. Both the line and load connections are made directly to the breaker lugs.
Are the thermal or magnetic trip thresholds adjustable on this model?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous (LI) protection settings are factory calibrated for 30 amps and cannot be modified in the field.
Can the FAL360301212 be utilized in DC control circuits?
Yes, this thermal-magnetic breaker is rated for 250VDC applications with a 10kA interrupting capacity, making it suitable for both AC and DC control panels.
Is the FAL360301212 part of a current or legacy product line?
The FAL series belongs to the legacy Square D F-Frame family. It is primarily sourced for direct replacements in existing control panels, switchboards, and older Square D enclosures rather than for new construction.
What are the conductor limits for the standard lugs on this breaker?
The factory lugs accommodate 14 AWG to 4 AWG conductors and are dual-rated for both copper and aluminum wire, providing flexibility for various field wiring conditions.
