Product FAQs
7 answersWhich enclosures and panelboards are compatible with the JGP36175?
This unit-mount breaker is designed for installation in Square D NF and NQ panelboards, QED switchboards, and custom industrial control panels.
What are the wire size limits and lug torque specs for the JGP36175?
The standard lugs accept 4 AWG to 4/0 AWG aluminum or copper wire. The required tightening torque for these standard lugs is 225 lb-in (25 Nm) using a 5/16-inch hex bit.
Does the JGP36175 come with lugs on both the line and load sides?
No. The P in the JGP part number indicates it is configured with terminal nuts on the line side (ON end) and standard lugs on the load side (OFF end). If your installation requires lugs on both ends, you will need to install a separate line-side lug kit or source the equivalent JGL variant.
How does the adjustable magnetic trip function work on this breaker?
The JGP36175 features a thermal-magnetic trip unit with a fixed thermal element for overload protection and an adjustable magnetic element for short circuits. The magnetic trip range can be dialed from 875A to 1750A to coordinate with your system fault current requirements.
What does the G in the JGP36175 part number indicate?
The G designates the breaker's interrupting capacity tier within the PowerPacT J-Frame family. It signifies a maximum fault current rating of 65kA at 240VAC, 35kA at 480VAC, and 18kA at 600VAC.
How is the JGP36175 physically mounted in a panel?
This is a unit-mount, bolt-on circuit breaker. It fastens directly to the panel or backpan using mounting screws and hard-wired connections, unlike I-Line variants that plug directly into a busbar.
Does this breaker include a push-to-trip feature for testing?
Yes, all PowerPacT J-Frame circuit breakers include an integral push-to-trip button on the front cover. This allows you to manually trip the breaker to verify the mechanical operation of the trip mechanism during routine maintenance.
