Product FAQs
7 answersIs the Square D FHL36070 still being manufactured?
No, the FHL36070 is an obsolete legacy F-frame circuit breaker that was discontinued by Schneider Electric in 2021.
What is the modern replacement for the FHL36070?
For new installations, the FHL36070 is replaced by the PowerPact H-frame series, specifically the HGL36070. Upgrading legacy panels to the H-frame may require verifying panelboard compatibility or using specific mounting hardware.
What type of panels accept the FHL36070?
This unit mount, feed-thru breaker is designed for installation in legacy Square D enclosures, switchboards, and panelboards that accept F-frame breakers. It is not compatible with I-Line plug-on distribution panels.
What is the recommended tightening torque for the FHL36070 lugs?
The standard AL100FA lugs used on this breaker should be torqued to 50 lb-in (5.6 N-m) for 14 to 1/0 AWG copper or aluminum wire.
Can I use aluminum wire with the FHL36070?
Yes, the factory-installed AL100FA lugs are dual-rated for both copper and aluminum conductors ranging from 14 AWG to 1/0 AWG.
What type of protection does the FHL36070 trip unit provide?
It features a fixed thermal-magnetic trip unit that provides standard long-time and instantaneous (LI) protection against overloads and short circuits. It does not include ground fault or arc fault protection.
What is the difference between the FAL36070 and the FHL36070?
The FHL36070 is the high-interrupting version of the standard FAL36070. While both are 70A F-frame breakers, the FHL model offers a higher interrupting capacity of 25kA at 480VAC, compared to the standard 18kA rating of the FAL model.
