Description
Part of the legacy F-Frame family, this 150-amp molded case circuit breaker delivers robust long-time and instantaneous trip functions. The unit features an adjustable magnetic trip mechanism to fine-tune short-circuit response. Designed for unit mount installations, the device integrates into GE A-Series panelboards and motor control centers. For modern upgrades, this model is replaced by the ABB Tmax XT4 series.Specifications

Product FAQs
5 answersHow is the THFK236150WL mounted in electrical distribution equipment?
This is a unit mount, feed-thru circuit breaker. It bolts directly to the backpan or chassis in GE A-Series panelboards, switchboards, and motor control centers rather than plugging onto a bus system.
What does the "WL" suffix in the THFK236150WL catalog number indicate?
The "WL" suffix designates that the breaker ships with factory-installed line and load lugs. These lugs accommodate copper or aluminum conductors ranging from 4 AWG to 300 kcmil.
How does the adjustable magnetic trip function work on this breaker?
While the thermal element provides fixed long-time overload protection, the adjustable magnetic element allows electricians to fine-tune the instantaneous short-circuit trip threshold to coordinate with downstream devices or specific load inrush currents.
What is the difference between GE TFK and THFK circuit breakers?
Both are built on the legacy GE F-Frame platform, but the THFK is the "Hi-Break" version. The "H" indicates a higher interrupting capacity (AIC rating) compared to standard TFK breakers.
Why might this breaker be labeled as either ABB or General Electric?
ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, this F-Frame breaker may feature either ABB or GE branding, but the physical dimensions, fit, and function remain identical.
