Description
The FHL36080G is a 3-pole, 80A thermal-magnetic MCCB from Square D's legacy F-Frame series. Built for commercial use, it delivers reliable long-time and instantaneous (LI) protection. Designed as a unit mount feed-thru breaker, it installs into Square D enclosures and switchboards. This discontinued model is replaced by the HGL36080. Rated for 65kAIC at 240V, this configuration features a factory-installed ground fault shunt trip (indicated by the G suffix) for enhanced safety.Specifications

Product FAQs
4 answersDoes the FHL36080G provide standalone ground fault protection?
No. While the G suffix indicates it has a factory-installed ground fault shunt trip, it requires an external sensing unit, such as the Square D GFM100FA Micrologic Ground Fault Module, to actually detect faults and trigger the breaker.
What does the G suffix mean in the FHL36080G catalog number?
The G suffix designates that the breaker includes a factory-installed ground fault shunt trip. This specific configuration is required when you need to pair the breaker with an external ground fault sensing module.
Is the FHL36080G still in active production?
No, the legacy Square D F-Frame series has been discontinued. It is typically replaced by the newer PowerPact H-Frame series, such as the base model HGL36080. You will need to verify accessory requirements, like the ground fault shunt trip, for your specific panel upgrade.
Will the FHL36080G plug into a Square D I-Line panelboard?
No, this is a unit-mount, feed-thru circuit breaker equipped with lugs on both the line and load sides. It does not have the plug-on jaw connectors required for I-Line bus installations.
