Description
A core component of GE's legacy J-Frame family, the TJK636600 is a 3-pole, 600A molded case circuit breaker. It utilizes an interchangeable thermal-magnetic trip unit, offering fixed long-time and adjustable instantaneous (LI) protection. Designed for unit-mount configurations, this breaker fits GE A-Series and J600 panelboards. Facilities looking to modernize can transition to the XT5N600 with a retrofit kit. Lugs are not included. It delivers a 30 kAIC interrupting rating at 480VAC.Specifications

Product FAQs
5 answersWhich panelboards and enclosures are compatible with the TJK636600?
This unit mount breaker is designed for installation in GE A-Series and J600 panelboards, as well as compatible GE switchboards and motor control centers.
What are the standard lug wire size requirements for this breaker?
The standard terminals accept two conductors per phase. For copper wire, the range is 4/0 AWG to 350 kcmil. For aluminum wire, the range is 300 kcmil to 500 kcmil.
How does the adjustable magnetic trip function operate on the TJK636600?
While the thermal overload protection is fixed at 600 amps, the magnetic trip is adjustable. This allows electricians to fine-tune the instantaneous short-circuit pickup threshold to coordinate with other protective devices in the system.
What type of protection does the LI trip function provide?
The LI designation indicates Long-Time and Instantaneous protection. Long-Time handles sustained overloads by heating a bimetallic strip, while the Instantaneous function uses a magnetic coil to trip immediately during high-fault short circuits.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions in 2018. Legacy GE molded case circuit breakers, including the J-Frame TJK series, are now managed under the ABB brand portfolio.
