Description
Providing specialized protection for industrial systems, the Square D FHL36100G is a 100A, 3-pole molded case circuit breaker. It comes equipped with a factory-installed ground fault shunt trip for advanced safety applications. Designed for unit mounting, this F-Frame breaker integrates into standard Square D panelboards and switchboards. When replacing this legacy unit, the HGL36100 serves as the substitute, provided ground fault requirements are verified. It features a thermal-magnetic trip.Specifications

Product FAQs
8 answersWhat does the "G" suffix in the FHL36100G catalog number indicate?
The "G" suffix indicates that this circuit breaker is equipped with a factory-installed ground fault shunt trip. This accessory is designed to be used with a compatible ground fault module, such as the GFM100FA, to provide ground fault protection for the circuit.
What does the "H" in the FHL series stand for?
In the Square D F-frame catalog numbering system, the "H" indicates a high interrupting capacity. This provides a higher fault current rating compared to standard FAL series breakers.
Are the trip settings on the FHL36100G adjustable?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time (thermal) and instantaneous (magnetic) trip functions are factory-set and cannot be adjusted in the field.
Can I install the FHL36100G in a Square D I-Line panelboard?
No, this is a unit-mount breaker with feed-thru lugs on both ends. It does not have the plug-on jaw connections required for I-Line panelboards. You will need an I-Line specific F-frame breaker for those applications.
What type of enclosures or panels is the FHL36100G compatible with?
This unit-mount F-frame breaker is designed for use in compatible Square D enclosures, switchboards, and panelboards. It features a feed-thru connection with lugs on both the line and load sides.
What type of wire can be used with the FHL36100G terminals?
The factory-installed lugs are dual-rated for both copper and aluminum (Cu/Al) conductors, accommodating wire sizes from 14 AWG up to 1/0 AWG. Ensure proper torque specifications are followed during installation.
Can the FHL36100G be used for both AC and DC applications?
Yes, this thermal-magnetic breaker is dual-rated for alternating current and direct current systems. It supports up to 600VAC and 250VDC, making it versatile for various industrial setups.
Is the FHL36100G a current production breaker or a legacy model?
The FHL36100G is part of the legacy Square D F-frame molded case circuit breaker family. While it is a legacy model, it remains widely used in existing industrial switchboards and motor control centers.
