Product FAQs
6 answersWhat does the WL suffix indicate on the THJK436150WL?
The WL suffix signifies that the breaker is factory-equipped with line and load side lugs. These terminals accept either a single 6 AWG to 600 kcmil conductor or two 2/0 AWG to 250 kcmil conductors per phase.
Does the THJK436150WL feature an adjustable trip unit?
Yes, it utilizes a thermal magnetic trip unit with fixed thermal protection for long-time overloads and an adjustable magnetic setting for instantaneous short-circuit protection. The trip unit itself is interchangeable.
Which enclosures are compatible with this TJK frame breaker?
This unit is designed for use with GE J600 series enclosures. It is also suitable for installation in compatible General Electric switchboards and motor control centers.
What is the mounting style for the THJK436150WL?
This is a unit mount, feed-thru circuit breaker. It bolts directly to the mounting pan or equipment chassis rather than plugging into a panelboard busbar.
