ABB / General Electric TJK436200WL Molded Case Circuit Breaker

The included line and load lugs accept either a single conductor from 6 AWG to 600 kcmil or dual conductors from 2/0 AWG to 250 kcmil. Both copper and aluminum wires are supported.

This unit mounts directly in GE J600 series enclosures, as well as compatible GE switchboards and motor control centers designed to accept unit-mount J-Frame breakers.

The thermal overload protection is fixed at 200 amps. However, the magnetic short-circuit trip threshold is adjustable, allowing for coordination with other protective devices in your electrical system.

The "WL" suffix indicates that the breaker is supplied from the factory with wire lugs installed on both the line and load sides, ready to accept copper or aluminum conductors.

ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, the TJK436200WL may carry either the GE or ABB logo, but the physical dimensions, mounting, and electrical characteristics remain identical.

Yes, it is rated for DC systems up to 500 Vdc with an interrupting capacity of 20 kA. Ensure proper wiring configurations for DC circuits as specified by the manufacturer and local electrical codes.

The TJK436200WL is a unit-mount breaker designed to be fastened to a backpan or enclosure. It does not plug into or bolt directly onto a panelboard busbar. It uses cable lugs for both line and load connections.

The LI designation stands for Long-Time and Instantaneous protection. The Long-Time function provides thermal overload protection, while the Instantaneous function provides magnetic short-circuit protection.
