Product FAQs
7 answers
Is the Square D FHL36080 still manufactured?
No, the FHL36080 is a legacy F-Frame circuit breaker that has been discontinued by Schneider Electric. It has been superseded by the PowerPact H-Frame series.
What is the direct replacement for the obsolete FHL36080?
The designated replacement is the PowerPact HGL36080. It provides the same 80A, 3-pole, 600VAC configuration and unit-mount design, but features a more compact footprint and upgraded performance.
How is the FHL36080 installed?
This is a unit-mount, feed-thru circuit breaker. It bolts directly to a mounting plate or backpan and uses mechanical lugs on both the line and load sides for wire connections.
What is the recommended lug torque for the FHL36080?
The factory-installed AL100FA mechanical lugs require a tightening torque of 50 lb-in (5.6 N.m) for 14 AWG to 1/0 AWG copper or aluminum conductors.
Can the FHL36080 be installed in Square D I-Line panelboards?
No. The FHL36080 is a unit-mount breaker designed for standard enclosures and switchboards. I-Line panelboards require a plug-on breaker with I-Line jaw connections on the line side.
What type of trip protection does the FHL36080 offer?
It features a non-interchangeable thermal-magnetic trip unit that provides fixed Long-Time (L) protection for overloads and Instantaneous (I) protection for short circuits.
Does the FHL36080 accept field-installable accessories?
Yes, legacy F-Frame breakers can accept select factory or field-installable accessories, such as shunt trips, auxiliary switches, and undervoltage releases, depending on the enclosure space.
