Product FAQs

5 answers
What does the WL suffix in the TJK636300WL catalog number indicate?

The WL suffix designates that this circuit breaker comes factory-equipped with both line and load lugs installed.

How does the trip unit function on this J-frame breaker?

It features a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element, allowing you to fine-tune the instantaneous short-circuit response.

Can the lugs on this breaker accept multiple conductors per phase?

Yes, the standard lugs can accommodate either a single conductor ranging from 6 AWG to 600 kcmil or two conductors ranging from 2/0 AWG to 250 kcmil (copper or aluminum) per terminal.

What type of mounting does the TJK636300WL require?

This is a unit-mount circuit breaker. It is designed to be bolted directly to the mounting pan or bus in compatible GE switchboards, motor control centers, and standalone enclosures.

Is this breaker a direct replacement for older GE J600 models?

Yes, the TJK636300WL belongs to the legacy GE J600 molded case circuit breaker family. It shares the standard 8-1/4 inch W x 3-13/16 inch D x 10-1/8 inch H dimensions, making it a drop-in replacement for existing J-frame spaces.
