Product FAQs
6 answersWhat does the "WL" suffix mean on the TJK436400WL?
The "WL" designates that the breaker is supplied with factory-installed lugs. It serves as a direct replacement for the base catalog number TJK436400 if you need the standard lug configuration.
Why might the TJK436400WL have an ABB or GE label?
ABB acquired GE Industrial Solutions, meaning legacy J-Frame breakers may arrive with either GE or ABB branding on the nameplate. Both versions are physically and electrically identical.
What wire sizes are compatible with the lugs on this breaker?
The included lugs can terminate one copper or aluminum conductor sized 6 AWG to 600 kcmil, or two conductors sized 2/0 AWG to 250 kcmil.
How does the trip unit operate on the TJK436400WL?
It uses a thermal magnetic trip system configured with a fixed thermal element for standard overload protection and an adjustable magnetic trip for instantaneous short-circuit protection.
Where is the TJK436400WL typically installed?
This J-Frame unit mount breaker is designed for installation in legacy GE J600 enclosures, motor control centers, and switchboards using a standard feed-thru bolted connection.
Can the TJK436400WL be used in DC circuits?
Yes, this breaker is rated for direct current applications. It provides a 20kA interrupting rating at both 250VDC and 500VDC.
