Product FAQs
8 answersWhat does the "SO" suffix mean in the JGL36175SO catalog number?
The "SO" suffix indicates that this breaker includes a factory-installed 24VDC shunt trip. This accessory allows the breaker to be tripped remotely by applying a 24VDC control voltage signal.
How do I identify the interrupting capacity tier from the JGL36175SO catalog number?
The second letter, "G", indicates the interrupting capacity tier for this PowerPacT J-Frame breaker. This specific tier provides 65kA at 240VAC, 35kA at 480VAC, and 18kA at 600VAC.
What does the "L" signify in the JGL36175SO catalog number?
The "L" indicates the terminal configuration. It specifies that the breaker is equipped with mechanical lugs on both the line and load sides, as opposed to busbar or plug-in connections.
How is the JGL36175SO catalog number structured for poles, voltage, and amperage?
In the Square D PowerPacT nomenclature, the "3" indicates a 3-pole configuration, the "6" specifies a 600VAC maximum voltage rating, and "175" denotes the 175-amp continuous current rating.
What equipment is the JGL36175SO circuit breaker designed to be installed in?
This unit-mount J-Frame breaker is designed for use in Square D NF panelboards, switchboards, motor control centers, and industrial enclosures.
What is the difference between a unit-mount JGL36175SO and an I-Line breaker?
The JGL36175SO is a unit-mount breaker, meaning it fastens directly to a mounting pan and uses wire lugs for the line-side connection. I-Line breakers, by contrast, plug directly into a specialized distribution busbar.
What wire sizes and materials are supported by the terminals on the JGL36175SO?
The factory-installed line and load lugs accept either copper or aluminum conductors ranging from 4 AWG to 4/0 AWG.
Are the trip settings on the JGL36175SO adjustable?
The thermal-magnetic trip unit features a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection.
