Product FAQs
8 answersWhat panelboards and equipment are compatible with the TFK236100?
This F-Frame breaker mounts directly into legacy GE A-Series panelboards, Spectra Series switchboards, and standard motor control centers requiring a bolt-on connection.
Is the GE TFK236100 still manufactured, or is there a direct replacement?
The TFK series is a legacy GE F-Frame breaker. Installations requiring this specific footprint can use exact replacements, or the system can be upgraded to the modern ABB Tmax XT4 platform using an approved retrofit kit.
Why might my TFK236100 breaker arrive with ABB branding instead of GE?
ABB acquired GE Industrial Solutions in 2018. Depending on the production batch, this F-Frame breaker may feature either GE or ABB branding, but the physical dimensions and performance specifications remain identical.
What does the adjustable magnetic trip on the TFK236100 allow me to do?
While the thermal overload protection is fixed, the adjustable magnetic trip lets electricians fine-tune the instantaneous short-circuit response threshold. This ensures proper selective coordination with downstream breakers and upstream main devices.
Can the TFK236100 be used in DC applications?
Yes, in addition to its AC ratings, this breaker is rated for up to 250VDC with a 10kA interrupting capacity, making it suitable for industrial DC control circuits or specific UPS applications.
What does the LI trip function code mean for this breaker?
The LI designation indicates that the thermal-magnetic trip unit provides Long-Time (L) protection against sustained overloads and Instantaneous (I) protection against sudden short circuits.
What are the wiring requirements for the TFK236100 lugs?
The standard load lugs accept copper or aluminum conductors ranging from 4 AWG to 300 kcmil. Electricians must ensure proper torque specifications are applied during installation to maintain a secure, code-compliant connection.
What safety precautions should be taken before installing the TFK236100?
Always de-energize the panelboard or switchboard before installation. Verify that the power is off using a properly rated voltage tester, and ensure the breaker's 22kAIC rating at 480V meets or exceeds the available fault current at the installation point.
