Designed to safeguard industrial electrical systems, this 110A, 3-pole molded case circuit breaker utilizes proven thermal-magnetic trip technology. The unit-mount configuration fits into PowerPacT H-Frame enclosures and control panels. It provides an upgrade path for obsolete KA36110 and KH36110 legacy breakers. Boasting a 65kA interrupting rating at 240VAC, it features an adjustable magnetic trip for tailored defense. The Visi-Trip flag simplifies troubleshooting.

Product FAQs
8 answers
Can the Square D HGL36110 be reverse fed?
Yes. Standard unit-mount PowerPacT H-frame thermal-magnetic circuit breakers with factory-sealed trip units are suitable for reverse connection.
What is the magnetic trip range for the HGL36110 circuit breaker?
The fixed thermal-magnetic trip unit on this 110A breaker has a magnetic hold current of 900A and a magnetic tripping current of 1700A.
Does the PowerPacT HGL36110 replace older Square D F-frame breakers?
Yes. The PowerPacT H-frame series is the direct replacement for obsolete 3-pole F-frame breakers like the FAL or FHL series. Because the physical footprint and mounting dimensions differ, panel modifications are typically required when retrofitting.
What does Unit Mount mean for the HGL36110 installation?
As a unit-mount circuit breaker, it installs using mounting screws on a backpan or enclosure rather than plugging into an I-Line bus. It includes standard line and load side lugs for feed-thru wiring.
What wire sizes are accepted by the standard lugs on this 110A breaker?
The factory-installed AL150HD lugs accept 14 AWG to 3/0 AWG aluminum or copper wire.
What does the G in the HGL36110 part number signify?
The G indicates the interrupting rating tier within the PowerPacT H-frame family. For this breaker, it provides a 65kAIC rating at 240VAC, 35kAIC at 480VAC, and 18kAIC at 600VAC.
Can the HGL36110 be used in DC control panels?
Yes. This breaker is rated for DC applications, providing an interrupting capacity of 20kAIC at both 250VDC and 500VDC.
Is this breaker rated for 100 percent continuous current?
No. The HGL36110 is a standard-rated breaker, meaning it is rated for 80 percent continuous current operation.
