Product FAQs
8 answersWhy is the TJK636450WL listed as both ABB and General Electric?
ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, this breaker may be branded as either ABB or GE, but the physical dimensions, mounting, and electrical specifications remain identical.
What does the WL suffix indicate on the TJK636450WL catalog number?
The WL suffix means the circuit breaker comes factory-equipped with copper/aluminum (Cu/Al) line and load lugs.
Which panelboards and enclosures are compatible with the TJK636450WL?
This J-Frame breaker is designed for use in GE J600 panelboards, switchboards, motor control centers, and standalone J-Frame enclosures.
What size wire do the included lugs on the TJK636450WL accept?
The lugs accept two 4/0 AWG to 350 kcmil copper conductors, or two 300 to 500 kcmil aluminum conductors per phase.
Can the TJK636450WL be used in DC power systems?
Yes, it is rated for DC applications up to 500VDC, providing an interrupting capacity of 20kAIC at both 250VDC and 500VDC.
Is the trip unit on the TJK636450WL adjustable?
The thermal (long-time) trip is fixed at 450A, but the magnetic (instantaneous) trip is adjustable to allow for precise coordination with downstream devices.
Does the TJK636450WL support field-installable accessories?
Yes, the TJK frame supports field-installable internal accessories, including shunt trips, auxiliary switches, and undervoltage releases.
What is the difference between GE TJK and TJJ circuit breakers?
