Product FAQs
8 answersWhat does the "WL" suffix indicate on the THFK224200WL?
The "WL" suffix signifies that the breaker includes factory-installed line and load lugs for feed-thru wiring. Standard models without this suffix typically do not include line-side lugs.
What is the modern replacement for the THFK224200WL?
As a legacy GE F-Frame breaker, it can be upgraded to the ABB Tmax XT3 series or the GE Spectra SFHA24AT0200. Note that specific mounting adapters or enclosure modifications may be necessary when upgrading.
Which panelboards and enclosures are compatible with this breaker?
The THFK224200WL is a unit-mount breaker designed to install into GE A-Series panelboards, Spectra switchboards, motor control centers, and standalone enclosures.
What frame family does the THFK224200WL belong to?
It belongs to the legacy GE F225 line of F-Frame molded case circuit breakers, which are widely used in older industrial power distribution systems.
What wire sizes are accepted by the lugs on this breaker?
The factory-installed lugs accommodate copper or aluminum conductors ranging from 4 AWG to 300 kcmil.
How does the trip unit operate on the THFK224200WL?
It utilizes an interchangeable thermal-magnetic trip unit. The thermal element provides fixed long-time overload protection, while the magnetic element is adjustable to allow precise coordination for instantaneous short-circuit protection.
Can the trip unit be swapped out on this breaker frame?
Yes, the THFK series features an interchangeable trip unit design. This allows you to change the amperage rating by installing a different trip unit without replacing the entire breaker frame.
Is the THFK224200WL rated for direct current (DC) applications?
Yes, in addition to its AC ratings, this breaker is rated for use in DC systems up to 250VDC, where it provides an interrupting capacity of 10 kAIC.
