Product FAQs
7 answersWhich panelboards and enclosures are compatible with the TJK436150 circuit breaker?
This J-Frame breaker is designed for use in GE A-Series panelboards, GE J600 panelboards, switchboards, and motor control centers. It utilizes a bolt-on mounting connection.
What is the maximum frame size for the TJK series?
The TJK436150 belongs to the GE J600 line of circuit breakers. While this specific model is equipped with a 150A trip unit, the J-Frame itself supports a maximum rating of 600 amps.
What wire sizes are accepted by the lugs on the TJK436150?
The factory lugs accept either one 6 AWG to 600 kcmil copper or aluminum wire, or two 2/0 AWG to 250 kcmil copper or aluminum wires per phase.
Can the GE TJK436150 be reverse fed?
No. According to GE and ABB specifications, TJK and THJK frame circuit breakers equipped with interchangeable trip units and line and load lugs are not suitable for reverse feed applications.
How does the trip unit function on this 150A breaker?
The TJK436150 features a thermal magnetic trip unit with a fixed thermal element for 150A continuous overload protection and an adjustable magnetic element for short-circuit protection.
Can the TJK436150 be used in DC power applications?
Yes, in addition to its AC ratings, this breaker is rated for DC applications. It provides an interrupting capacity of 20kA at both 250VDC and 500VDC.
Is the GE TJK436150 still actively manufactured, or is there a replacement?
The TJK series is a legacy J-Frame product line that has been transitioned to limited production by ABB. For new installations or complete upgrades, ABB recommends transitioning to the Tmax XT series, such as the XT4, which requires a retrofit kit for existing enclosures.
