Product FAQs
6 answersWhat types of electrical equipment are compatible with the TFL236175 breaker?
This F-frame breaker is designed for use in GE A-Series panelboards, switchboards, and motor control centers. It features a bolt-on unit mount configuration for secure installation in these enclosures.
How does the adjustable magnetic trip function work on this breaker?
The TFL236175 features a fixed thermal and adjustable magnetic (LI) trip unit. While the continuous current rating is fixed at 175 amps, the instantaneous magnetic trip can be adjusted to coordinate with downstream protective devices and prevent nuisance tripping during motor inrush currents.
What wire sizes are accepted by the standard lugs on the TFL236175?
The standard lugs accept copper or aluminum conductors ranging from 4 AWG to 300 kcmil. Always verify the specific torque requirements printed on the breaker label to ensure a safe and compliant termination.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions in 2018. As a result, legacy GE F-frame molded case circuit breakers like the TFL236175 may be branded as either GE or ABB depending on the manufacturing date, but they are physically and electrically identical.
Can this breaker be used in direct current applications?
Yes, the TFL236175 is rated for DC applications up to 250VDC, providing an interrupting capacity of 10kA. It is suitable for both AC and DC systems within its specified voltage limits.
What safety procedures are required when installing this F-frame breaker?
Installation must be performed by a licensed electrician. Ensure all power sources to the panelboard or switchboard are completely de-energized, tested with a reliable voltage meter, and locked out before mounting the breaker or terminating the conductors.
