Product FAQs
6 answers
What type of panels accept the FHL36060G breaker?
This unit-mount breaker is designed for Square D enclosures, switchboards, and control panels. It fastens directly to the backpan for feed-thru applications and is not compatible with I-Line plug-on bus systems.
What is the current replacement for the legacy FHL36060G circuit breaker?
Schneider Electric designates the PowerPact B-Frame molded case circuit breaker as the direct replacement for legacy 15A to 125A F-frame applications. The B-Frame offers a smaller unit-mount footprint while maintaining compatibility for retrofits.
How are wire connections made on the FHL36060G?
The breaker features factory-installed line and load side lug terminals. These lugs accept 14 AWG to 1/0 AWG copper or aluminum conductors, making it suitable for standard feed-thru wiring configurations.
What protection features are included in the FHL36060G?
It utilizes a fixed thermal-magnetic trip unit with long-time and instantaneous functions to clear overloads and short circuits. Additionally, this specific model includes a ground fault shunt trip mechanism for remote tripping when integrated with external ground fault sensors.
Can the FHL36060G be installed in DC control circuits?
Yes, this breaker is rated for up to 250VDC with a 10kA interrupting capacity, making it suitable for DC control panels, battery systems, and other direct current applications alongside its standard AC ratings.
What is the difference between Square D FHL and FAL circuit breakers?
Both are legacy F-frame breakers, but the FHL series features a higher interrupting capacity than the standard FAL series. The "L" in both catalog numbers indicates they are unit-mount breakers with lugs on both the line and load sides.
