Product FAQs
8 answersWhat does the "WL" suffix indicate on the THJK636600WL breaker?
The "WL" suffix indicates that the breaker comes factory-equipped with line and load lugs for immediate feed-thru connection.
What is the difference between the GE TJK and THJK breaker series?
The THJK series is a "Hi-Break" model featuring a higher interrupting capacity than the standard TJK series. Both fit the same J600 frame footprint.
Which enclosures are compatible with the THJK636600WL?
This unit mounts in GE J600 series enclosures, as well as compatible GE switchboards and motor control centers.
How is the instantaneous trip adjusted on this breaker?
The magnetic trip is adjustable via a dial on the front of the trip unit, allowing you to set the instantaneous trip threshold to match your specific load requirements.
What wire size and material can be used with the factory lugs?
The included lugs accept two conductors per phase, ranging from 4/0 AWG to 500 kcmil, and are compatible with both copper and aluminum wiring.
Can I replace an older GE THJK636600 with the THJK636600WL?
Yes, the THJK636600WL is the direct replacement. The base catalog number is THJK636600, and the "WL" confirms that the mounting lugs are included.
Does this breaker provide ground fault protection?
No, the THJK636600WL features standard thermal-magnetic trip functions for overload and short-circuit protection. It does not include integrated equipment ground fault protection.
Can the trip unit be swapped out on the THJK636600WL?
Yes, the THJK636600WL features an interchangeable trip unit design within the J600 frame, allowing the thermal-magnetic trip elements to be replaced without removing the entire breaker frame.
