Product FAQs
6 answersWill I receive an ABB or General Electric branded TJK436250WL breaker?
ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, this breaker may feature either ABB or GE branding. The physical dimensions, fit, and technical specifications remain identical regardless of the label.
What type of panelboards and enclosures is the TJK436250WL compatible with?
This J-frame molded case circuit breaker is designed for use in GE J600 panelboards, switchboards, and motor control centers. It serves as a direct-fit replacement for legacy infrastructure, avoiding the need to retrofit for newer series like the Tmax XT5.
Does the TJK436250WL come with lugs, and what wire sizes are accepted?
Yes, the WL suffix indicates that lugs are included. The terminals accept either one 6 AWG to 600 kcmil copper or aluminum wire, or two 2/0 AWG to 250 kcmil wires per phase.
Is the trip unit on the TJK436250WL adjustable?
This breaker features a thermal-magnetic trip unit with fixed thermal (long-time) protection and an adjustable magnetic (instantaneous) trip function. The trip unit itself is interchangeable within the TJK4 frame.
What is the maximum frame size for the TJK436250WL?
While equipped with a 250A trip unit, this breaker is built on the GE TJK4 frame, which has a maximum capacity of 400A. The interchangeable design allows for field modifications if system amperage requirements change.
