Product FAQs
7 answersWhat do the letters in the HGL36050 catalog number signify?
"H" indicates the PowerPacT H-Frame. "G" specifies the interrupting rating tier, which is 35kA at 480VAC. "L" means it is a unit-mount breaker with lugs on both the line and load sides. The "3" stands for 3-pole, "6" for 600VAC maximum voltage, and "050" for the 50-amp rating.
What is the difference between the Square D HGL36050 and HGA36050?
The HGL36050 is a unit-mount circuit breaker with feed-thru lugs on both the line and load sides. The HGA36050 is an I-Line circuit breaker designed to plug directly into an I-Line panelboard bus on the line side, with lugs on the load side.
Which lug kit is standard on the HGL36050?
This breaker comes standard with AL150HD lugs on both the line and load sides. These lugs accept 14 AWG to 3/0 AWG aluminum or copper wire.
Is the HGL36050 suitable for reverse feeding?
Yes. Because it is a standard unit-mount thermal-magnetic breaker, the HGL36050 has a sealed trip unit and is suitable for reverse-feed applications.
Can the HGL36050 be installed as a main breaker in a Square D panelboard?
Yes, this breaker is compatible for use as a main breaker in NF and NQ panelboards. You will need the appropriate main breaker installation kit specific to your panelboard type and ampacity.
What does the LI trip function indicate on this H-Frame breaker?
The LI designation means the thermal-magnetic trip unit provides Long-Time (L) overload protection and Instantaneous (I) short-circuit protection. On the HGL36050, both the thermal and magnetic trip points are fixed and non-adjustable.
How can I manually test the tripping mechanism on the HGL36050?
The breaker features an integral push-to-trip button on the front cover. Pressing this button manually trips the breaker, allowing you to verify the mechanical operation of the trip mechanism and ensure the handle moves to the center tripped position.
