Part of the PowerPacT J-Frame family, this 200-amp molded case circuit breaker provides reliable thermal-magnetic protection for commercial and industrial facilities. The unit features fixed thermal and adjustable magnetic trip settings for precise coordination. Designed with a unit mount configuration, it installs into Square D enclosures, switchboards, and motor control centers. It serves as a drop-in replacement for legacy KH36200 models. Rated for 65kAIC at 480VAC, it includes Visi-Trip.
Which obsolete Square D circuit breaker does the JJL36200 replace?
The JJL36200 serves as the modern PowerPacT drop-in replacement for the legacy 200A Square D KH36200 unit-mount circuit breaker.
What is the adjustment range for the magnetic trip on the JJL36200?
This breaker features a fixed 200A thermal overload setting, but the instantaneous magnetic short-circuit pickup is adjustable. A front-mounted dial allows you to tune the magnetic trip point anywhere between 1000A and 2000A to achieve proper system coordination.
Are line and load lugs included with the JJL36200 circuit breaker?
Yes, this feed-thru breaker comes factory-equipped with mechanical lugs (part number AL250JD) on both the line and load ends. These standard lugs accept one 3/0 AWG to 350 kcmil aluminum or copper wire per phase.
Can the JJL36200 breaker be reverse-fed?
Yes, this unit-mount circuit breaker is approved for reverse-feed applications. Incoming line power can be safely landed on either the top or bottom terminals without compromising the thermal-magnetic protection capabilities.
How does the visual trip indicator work on this J-frame breaker?
The JJL36200 includes a Visi-Trip mechanism. In the event of an overcurrent or short circuit, the operating handle moves to the center position and displays a highly visible red flag, making it easy to quickly locate the tripped breaker inside a dark or crowded switchboard.
Does the JJL36200 have a manual trip test feature?
Yes, it features an integral push-to-trip button on the front cover. This allows panel builders and electricians to manually trip the breaker to verify the mechanical operation of the toggle mechanism and test any field-installed accessories like auxiliary switches.
