Description
Built for commercial and industrial applications, the THFK236100WL is a 3-pole, 100A molded case circuit breaker from GE's legacy F-Frame family. It installs into traditional A-Series panelboards, motor control centers, and switchboards. As a discontinued unit, it serves as an exact replacement for existing setups, or can be substituted with Spectra SFHA36AT0100 or Tmax XT3 models. Rated for 65kAIC at 240V, it features an interchangeable thermal-magnetic trip and includes TCAL24 lugs.Specifications

Product FAQs
6 answersWhat does the "WL" suffix mean in the THFK236100WL catalog number?
The "WL" suffix indicates that the circuit breaker comes factory-equipped with wire lugs on both the line and load sides. These lugs accept 4 AWG to 300 kcmil copper or aluminum conductors.
What is the difference between GE TFK and THFK circuit breakers?
Both are part of the legacy GE F225 line (F-Frame) and share identical physical dimensions and interchangeable trip units. The THFK is the high-interrupting capacity version (Hi-Break), offering higher fault protection ratings than the standard TFK frame.
Are the trip units on the THFK236100WL interchangeable?
Yes, unlike the TFJ series which has a fixed trip, the TFK and THFK frames feature interchangeable thermal-magnetic trip units. This allows panel builders to swap the trip unit without removing the entire breaker frame from the switchboard.
Is the magnetic trip setting adjustable on this breaker?
Yes. While the thermal overload protection is fixed at 100A, the instantaneous magnetic trip is adjustable. This allows electricians to fine-tune the short-circuit response for proper coordination with downstream devices.
What equipment accepts the THFK236100WL breaker?
This unit-mount F-Frame breaker is designed for legacy General Electric power distribution equipment, including A-Series panelboards, motor control centers (MCCs), switchboards, and standalone industrial enclosures.
Is the GE THFK236100WL an obsolete or legacy breaker?
Yes, the GE F-Frame is a legacy product line. Following ABB's acquisition of GE Industrial Solutions, exact replacements may carry either the GE or ABB brand. For complete panel upgrades, this frame is often retrofitted with the newer ABB Tmax XT series.
