Product FAQs
6 answersWhat panelboards and switchboards accept the JRA36200?
This breaker is designed for use in Square D I-Line panelboards and switchboards. It features a plug-on I-Line bracket on the line side and mechanical lugs on the load side.
What is the magnetic trip adjustment range for this breaker?
The JRA36200 features an adjustable magnetic trip with a range of 1000A (Low) to 2000A (High). The thermal trip is fixed at 200A.
What is the recommended lug torque for the load side terminals?
The load side lugs require a tightening torque of 230 lb-in (26 N.m) for 3/0 AWG to 350 kcmil aluminum or copper wire.
What does the "R" in JRA36200 signify?
The "R" indicates the interrupting rating tier within the PowerPacT J-Frame series. R-interrupting breakers deliver 200kAIC at 240VAC and 480VAC, and 100kAIC at 600VAC.
Can the JRA36200 be reverse fed?
No. Because it utilizes an I-Line plug-on connection on the line side, this breaker is marked for line and load and is not suitable for reverse-fed applications.
Is this breaker a direct replacement for older Square D models?
Yes, PowerPacT J-Frame I-Line breakers like the JRA36200 can serve as direct upgrades for legacy Square D K-Frame I-Line breakers, including KA, KC, and KH models of the same amperage and pole configuration.
