Description
Engineered for industrial applications, the Square D HJL26080 is a 2-pole, 80A MCCB from the PowerPacT H-Frame family. It provides robust long-time and instantaneous (LI) protection for motor control centers. This unit mount breaker features factory-installed lugs for integration into NQ or NF panelboards. It also replaces discontinued FH26080 legacy F-Frame breakers. Rated 65 kAIC at 480VAC, this current-limiting device includes a Visi-Trip indicator for rapid fault identification.Specifications

Product FAQs
8 answersWhat types of enclosures and panels are compatible with the HJL26080?
This unit mount breaker is designed for use in Square D NQ and NF panelboards, switchboards, industrial control panels, and motor control centers. It is not compatible with I-Line panelboards, which require a plug-on mounting style.
How does a unit mount breaker like the HJL26080 install into a panel?
Unit mount, or feed-thru, breakers install using mounting screws and connect to the circuit using wire lugs on both the line and load sides. They do not plug into or bolt directly onto a busbar.
What wire sizes and materials are accepted by the standard lugs on this breaker?
The factory-installed lugs accept wire gauges from 14 AWG to 3/0 AWG. They are rated for both aluminum and copper conductors.
What does the J in the HJL26080 part number indicate?
The J designates the interrupting rating tier within the Square D PowerPacT H-Frame series. It indicates a high interrupting capacity of 100kA at 240VAC, 65kA at 480VAC, and 25kA at 600VAC.
Can the HJL26080 be used in DC applications?
Yes, this breaker is rated for use in DC circuits up to 250VDC, with a maximum interrupting rating of 20kA at that voltage.
What type of trip unit is installed in the HJL26080?
It features a fixed thermal magnetic trip unit with Long-Time (L) and Instantaneous (I) trip functions. Both the thermal and magnetic trip thresholds are fixed and cannot be adjusted in the field.
What is the standard replacement lug kit for the HJL26080?
The standard replacement mechanical lug kit for 15A to 150A PowerPacT H-Frame breakers is part number AL150HD.
What safety precautions should be taken before installing the HJL26080?
Always de-energize the panelboard or switchboard before installation. Verify that the system voltage and available fault current do not exceed the breaker's maximum ratings of 600VAC and 25kAIC at 600VAC.
