Product FAQs
8 answersWhat does the "SA" suffix mean in the JGL36225SA catalog number?
The "SA" suffix indicates that this circuit breaker includes a factory-installed shunt trip. This accessory is typically rated for 110 to 130 VAC or 125 VDC, allowing the breaker to be tripped remotely for safety or control purposes.
What do the letters "JGL" indicate in this Square D part number?
In the PowerPacT nomenclature, "J" designates the J-Frame size. The "G" specifies the interrupting rating tier (65kA at 240VAC, 35kA at 480VAC), and the "L" indicates that the breaker is supplied with factory-installed lugs on both the line and load sides.
Is the trip unit on the JGL36225SA adjustable?
Yes, this thermal-magnetic breaker features a fixed thermal trip for long-time overload protection and an adjustable magnetic trip setting, allowing panel builders to fine-tune the instantaneous short-circuit response.
What does "Unit Mount" mean for the JGL36225SA?
Unit mount, also known as feed-thru mounting, means the breaker is designed to be individually bolted or bracket-mounted to a backpan in an enclosure or control panel. It is not designed to plug onto an I-Line busway.
What wire sizes and materials are compatible with the lugs on this breaker?
The factory-installed line and load lugs accept either aluminum or copper conductors ranging from 3/0 AWG to 350 kcmil.
What types of panels and enclosures are compatible with this J-Frame breaker?
The JGL36225SA is designed for use in Square D J-Frame enclosures, switchboards, motor control centers, and industrial control panels.
Can the JGL36225SA be used in DC power systems?
Yes, this breaker is rated for DC applications up to 500VDC. It provides an interrupting capacity of 20kA at both 250VDC and 500VDC.
What do the "LI" trip functions stand for on this breaker?
The "LI" designation means the breaker provides Long-Time (L) protection against sustained overloads and Instantaneous (I) protection against severe short circuits.
