Product FAQs

8 answers
What panelboards and enclosures are compatible with the JGL36175AA?

This unit mount breaker is designed for use in Square D NF panelboards, switchboards, motor control centers, and industrial enclosures.

What does the AA suffix in the JGL36175AA catalog number indicate?

The AA suffix means the circuit breaker is factory-equipped with a standard 1A/1B auxiliary switch. This provides one normally open (NO) and one normally closed (NC) contact for remote signaling or control applications.

How do I adjust the trip settings on this breaker?

The JGL36175AA features a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection. The magnetic trip threshold can be adjusted using the dial located on the front face of the trip unit.

What is the adjustable magnetic trip range for the JGL36175AA?

The instantaneous magnetic trip threshold can be adjusted from a low setting of 875A up to a high setting of 1750A. This allows for precise coordination with other protective devices in your electrical system.

What is the difference between the JGL36175AA and the JGA36175?

The JGL36175AA is a unit mount breaker with feed-thru lugs on both the line and load sides. The JGA36175 is the I-Line version, which features a plug-on jaw connection on the line side for use specifically in Square D I-Line panelboards and switchboards.

What does the G in the JGL36175AA catalog number signify?

The G indicates the breaker's interrupting rating tier within the PowerPacT J-Frame family. For this specific breaker, the G-rating provides 35 kA of interrupting capacity at 480VAC and 65 kA at 240VAC.

Does this breaker provide both overload and short-circuit protection?

Yes, the JGL36175AA uses a thermal-magnetic trip unit. The thermal element provides long-time protection against overloads, while the magnetic element provides instantaneous protection against short circuits.

How is the JGL36175AA mounted?

This is a unit mount circuit breaker. It is designed to be individually mounted onto a backpan or mounting plate using screws, rather than plugging directly into a busbar system.
