Description
Belonging to the legacy J-Frame family, this 200A molded case circuit breaker provides reliable long-time and instantaneous (LI) trip functions. The "WL" suffix indicates factory-installed line and load lugs. Designed for unit-mount configurations, it installs into GE A-Series panelboards, switchboards, and J600 enclosures. Rated to handle 65kA fault currents at 240V, the thermal-magnetic mechanism ensures consistent performance. It can be replaced by the Tmax XT4 using a retrofit kit.Specifications

Product FAQs
8 answersWhat enclosures and panelboards are compatible with the THJK436200WL?
This J-frame breaker is designed for use in GE J600 enclosures, GE A-Series panelboards, GE switchboards, and GE motor control centers.
What wire sizes and materials are accepted by the lugs on this breaker?
The factory lugs accept either one 6 AWG to 600 kcmil copper or aluminum conductor, or two 2/0 AWG to 250 kcmil copper or aluminum conductors per phase.
How does the adjustable magnetic trip function work on the THJK436200WL?
While the thermal overload protection is fixed at 200 amps, the magnetic short-circuit trip point can be adjusted in the field to coordinate with downstream devices and specific load inrush currents.
Is the THJK436200WL considered an ABB or GE breaker?
ABB acquired GE Industrial Solutions in 2018. This breaker may be branded as either GE or ABB depending on the manufacturing date, but the form, fit, and function remain identical.
Does this breaker mount onto a DIN rail or plug into a busbar?
No, the THJK436200WL is a unit-mount breaker. It must be bolted directly to the mounting pan or chassis and wired as a feed-thru device using the provided lugs.
Can this breaker be used in DC voltage applications?
Yes, it is rated for DC applications up to 500VDC, providing 40kA interrupting capacity at 250VDC and 20kA at 500VDC.
What does the LI trip function code indicate for this MCCB?
The LI designation means the breaker provides Long-Time (thermal) protection against overloads and Instantaneous (magnetic) protection against short circuits.
What does the TJK frame designation mean for this breaker?
The TJK frame is part of the legacy GE J-Frame family. It indicates the physical dimensions and mounting footprint, ensuring it fits into spaces designed for standard J-Frame breakers.
