Built for heavy-duty power distribution, the Square D JGA36200 is a 3-pole, 200A PowerPacT J-Frame MCCB. It utilizes thermal-magnetic trip technology to deliver precise Long-Time and Instantaneous (LI) protection for industrial facilities. This breaker mounts into Square D I-Line panelboards and switchboards. It can also be used as a replacement for the older KA36200 breaker. With a 35kAIC rating at 480VAC, it safely handles high fault currents and includes a Visi-Trip indicator.
Which panelboards are compatible with the JGA36200 circuit breaker?
The JGA36200 is an I-Line style breaker designed strictly for Square D I-Line panelboards and switchboards. It will not mount in standard unit-mount enclosures, NQ, NF, or QO load centers.
Is there a unit-mount equivalent for the JGA36200?
Yes. If your application requires mechanical lugs on both the line and load sides rather than the I-Line plug-on connection, the direct unit-mount equivalent is the Square D JGL36200.
What does the "G" indicate in the JGA36200 catalog number?
The "G" designates the interrupting rating tier within the Square D PowerPacT J-Frame family. For this breaker, the G-rating provides 65kA at 240V, 35kA at 480V, and 18kA at 600V. The "A" following it indicates the I-Line plug-on connection style.
How is the JGA36200 installed into the panel?
This breaker features a plug-on line side connection that pushes directly onto the bus stack of an I-Line panelboard. The load side utilizes standard mechanical lugs to terminate your conductors, accepting 3/0 AWG to 350 kcmil copper or aluminum wire.
What are the magnetic trip adjustment settings for this 200A breaker?
The JGA36200 utilizes a thermal-magnetic trip unit with a fixed thermal element and an adjustable magnetic element. The magnetic trip range can be adjusted between a 1000A hold setting and a 2000A trip setting to customize short-circuit protection.
