Product FAQs
9 answersWhat equipment is compatible with the RJF36200 circuit breaker?
This PowerPacT R-frame breaker is engineered for unit-mount installations. It is directly compatible with Square D QED Switchboards, Model 6 Motor Control Centers, and Power-Style Switchboards.
How is the RJF36200 connected during installation?
This model uses a feed-thru busbar connection for both the line and load sides. It does not include standard cable lugs, so you must use busbar mounting hardware or purchase separate lug kits to terminate cables.
What protection functions does the ET 1.0I trip unit provide?
The factory-installed ET 1.0I electronic trip unit delivers Long-Time and Instantaneous (LI) overcurrent protection. It features a fixed thermal threshold and an adjustable magnetic setting to fine-tune the short-circuit response.
What does the J stand for in the RJF36200 catalog number?
In the Square D PowerPacT nomenclature, the J designates the interrupting capacity tier. This specific frame provides a 65kAIC rating at 480VAC and a 100kAIC rating at 240VAC.
Is the RJF36200 rated for continuous 2000A loads?
No, this standard model is 80 percent rated. Under National Electrical Code guidelines, continuous loads lasting three hours or more should not exceed 1600 amps. A 100 percent rated version requires a different catalog number.
What wire sizes are supported if I install lug kits on this breaker?
When equipped with the appropriate mechanical lug kits instead of the standard busbar connections, the terminals can accept aluminum or copper conductors ranging from 3/0 AWG to 750 kcmil.
Can I swap the ET 1.0I trip unit for a MicroLogic model?
No, the basic ET 1.0I electronic trip unit on this breaker is not field-interchangeable. If your application requires advanced communication capabilities or PowerLogic metering, you must source a breaker originally built with a MicroLogic trip unit.
What safety standards apply to this 2000A R-frame breaker?
It is UL 489 listed and CSA certified for North American applications, and it complies with IEC 60947-2 standards for molded case circuit breakers in industrial power distribution systems.
Can this breaker be used in 600VAC systems?
Yes, the RJF36200 is rated for up to 600VAC. However, the interrupting capacity drops to 25kAIC at 600VAC, compared to its 65kAIC rating at 480VAC.
