Product FAQs
5 answersCan the JGL26225 be installed in a Square D I-Line panelboard?
No, the JGL26225 is a unit-mount breaker designed for feed-thru connections using standard wire lugs. It does not have the plug-on jaw brackets required for mounting in an I-Line bussing system.
What wire sizes are supported by the factory lugs on this breaker?
The standard factory-installed lugs accommodate a single conductor per phase, accepting wire sizes from 3/0 AWG up to 350 kcmil. The lugs are dual-rated for use with either copper or aluminum conductors.
How does the thermal-magnetic trip unit function on this J-Frame breaker?
It features a fixed thermal element for long-time overload protection and an adjustable magnetic element. The magnetic dial allows installers to manually set the instantaneous short-circuit trip threshold to meet specific system coordination requirements.
What do the characters in the JGL26225 catalog number represent?
In the Square D PowerPacT nomenclature, "J" represents the frame size. "G" indicates the interrupting rating tier. "L" specifies unit mounting with standard lugs on both the line and load sides. "2" indicates a two-pole configuration, "6" denotes the 600VAC voltage rating, and "225" specifies the 225-ampere rating.
What types of equipment are suitable for mounting this breaker?
Beyond standalone Square D J-Frame enclosures, this unit-mount breaker is commonly installed in industrial control panels, motor control centers, and switchboards that accept standard feed-thru configurations.
