Product FAQs
7 answers
What does the G in the HGL26090 catalog number signify?
The G indicates the interrupting rating performance level of the breaker. For this PowerPacT H-Frame model, it signifies a rating of 65kA at 240VAC, 35kA at 480VAC, and 18kA at 600VAC.
What does the L in the HGL prefix stand for?
The L indicates the termination type. It means the breaker is configured with lugs on both the line and load sides for unit mounting.
What is the recommended tightening torque for the lugs on the HGL26090?
This breaker typically uses the AL150HD lug kit. The tightening torque is 44 lb-in (5 N.m) for 14 AWG to 10 AWG wire, and 124 lb-in (14 N.m) for 8 AWG to 3/0 AWG wire.
Can the Square D HGL26090 be reverse fed?
Yes. Because it uses a standard thermal magnetic trip unit and does not have specific Line and Load markings, it is suitable for reverse feeding applications.
Does the PowerPacT HGL26090 replace older Square D F-frame breakers?
Yes, the PowerPacT H-frame series is the modern replacement for legacy Square D F-frame breakers like the FAL or FHL series. However, because the physical dimensions and mounting footprints differ, retrofitting may require panel modifications or adapter kits.
What type of enclosures or panels are compatible with this breaker?
The HGL26090 is a unit mount breaker designed for use in industrial control panels, switchboards, and dedicated PowerPacT H-Frame enclosures. It is not compatible with I-Line panelboards, which require a plug-on bracket.
Can I adjust the trip settings on the HGL26090?
This breaker features a thermal magnetic trip unit with a fixed thermal element for overload protection and an adjustable magnetic element for short-circuit protection.
