Description
Operating in commercial environments, the GE TFL236150 is a 150A molded case circuit breaker. It provides essential protection for 3-phase electrical systems. This unit-mount breaker integrates into GE A-Series panelboards. When modernizing, it is replaced by the XT4HU3150BFF000XXX model, requiring specific retrofit kits. The breaker features a thermal magnetic trip unit with LI functions. It provides a 65kAIC rating at 480VAC and includes factory-installed load lugs.Specifications

Product FAQs
5 answersWhat is the modern ABB equivalent for the legacy GE TFL236150?
When modernizing or replacing this legacy GE breaker, the direct ABB equivalent is the Tmax XT series model XT4HU3150BFF000XXX. Note that installing the newer XT4 breaker into legacy GE A-Series panelboards requires a specific retrofit kit.
Will the TFL236150 arrive with GE or ABB branding?
Because ABB acquired GE Industrial Solutions in 2018, legacy GE breakers like the TFL236150 may feature either GE or ABB branding on the front label depending on the manufacturing date. The physical dimensions, fit, and internal components remain identical regardless of the logo.
How does the adjustable magnetic trip function work on the TFL236150?
This breaker features a thermal-magnetic trip unit with an LI (Long-Time and Instantaneous) configuration. While the thermal overload protection is fixed at 150 amps, the magnetic instantaneous trip is adjustable. This allows electricians to fine-tune the short-circuit pickup threshold to coordinate with other protective devices in the system.
Does the TFL236150 provide current-limiting protection?
Yes, the GE TFL series operates as a current-limiting circuit breaker. During a severe short circuit, it is designed to trip rapidly and limit the peak let-through current and energy, providing enhanced protection for downstream electrical components.
How is the TFL236150 secured inside the panelboard?
This is a unit-mount, bolt-on circuit breaker. It requires bolted connections to the busbar, which provides a secure, high-vibration-resistant installation commonly required in industrial switchboards and motor control centers.
