Product FAQs
7 answersWhat equipment is compatible with the THFK236175WL circuit breaker?
This unit-mount breaker is designed for installation in GE A-Series panelboards, switchboards, motor control centers, and standalone enclosures.
What does the WL suffix mean in the THFK236175WL catalog number?
The WL suffix indicates that the breaker is factory-assembled with both line and load lugs included. If the lugs were not required for a specific bus connection, the WL would be omitted from the part number.
What wire gauge range is supported by the lugs on this 175A breaker?
The factory-installed lugs accept copper or aluminum conductors ranging from 4 AWG to 300 kcmil.
What frame size is the THFK236175WL?
This breaker is part of the GE F225 Line, commonly referred to as an F-Frame molded case circuit breaker.
How does the trip unit operate on this F225 frame breaker?
It utilizes an interchangeable thermal-magnetic trip unit. It provides fixed thermal protection for long-time overloads and features an adjustable magnetic trip for instantaneous short-circuit protection.
What is the difference between GE TFK and THFK circuit breakers?
The THFK series is the high-interrupting capacity version of the standard TFK series. While they share the same F225 physical frame, the THFK236175WL offers higher fault current ratings, such as 65kAIC at 240VAC and 25kAIC at 480VAC.
What are the safety considerations for applying this breaker on a 480V or 600V system?
When installing this breaker, verify that the available fault current at the load terminals does not exceed its maximum interrupting capacity of 25kA at 480VAC or 18kA at 600VAC. Proper torque must also be applied to the 4 AWG to 300 kcmil lugs to prevent thermal issues.
