Product FAQs
6 answersWhat enclosures or panelboards are compatible with the TJK636400?
The TJK636400 is designed for unit-mount configurations and fits legacy GE J600 and A-Series panelboards, as well as compatible switchboards and motor control centers.
What is the difference between the GE TJK636400 and THJK636400 circuit breakers?
Both are 400A, 3-pole J-Frame breakers, but they have different interrupting ratings. The TJK636400 has a standard interrupting capacity of 30kAIC at 480V, while the THJK636400 features a higher interrupting capacity for systems with greater available fault current.
Is the GE TJK636400 still actively manufactured?
Following ABB acquiring GE Industrial Solutions, the TJK series was transitioned to a limited legacy status. Facilities looking to modernize or replace this breaker can transition to the ABB Tmax XT series, specifically the XT5 frame, using a retrofit kit.
Can the TJK636400 be used in direct current applications?
Yes, this thermal-magnetic breaker is rated for DC systems. It provides an interrupting rating of 20kAIC at both 250VDC and 500VDC.
How is the trip unit configured on the TJK636400?
This breaker features an interchangeable thermal-magnetic trip unit with LI functions. The thermal long-time protection is fixed at 400 amps, while the magnetic instantaneous protection is adjustable to coordinate with your specific system requirements.
What wire sizes are accepted by the standard lugs on the TJK636400?
When equipped with standard lugs, the breaker accepts either two 4/0 AWG to 350 kcmil copper wires, or two 300 kcmil to 500 kcmil aluminum wires per phase.
