Product FAQs
5 answersWhat equipment is the GE TFK236150 circuit breaker compatible with?
It is designed for direct bolt-on installation in legacy GE A-Series panelboards, Spectra Series switchboards, and motor control centers.
What wire sizes are accepted by the standard lugs on the TFK236150?
The standard lugs accommodate wire gauges ranging from 4 AWG to 300 kcmil. Ensure proper torque specifications are followed during installation to maintain a secure connection.
How does the adjustable magnetic trip work on the TFK236150?
This breaker uses a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection. The magnetic dial allows electricians to fine-tune the instantaneous trip threshold based on the specific load requirements.
Can the trip unit be replaced on the TFK236150?
Yes, the TFK series features an interchangeable trip design. The 150A trip unit can be removed and replaced without needing to swap out the entire breaker frame.
Is the GE TFK236150 an active or legacy circuit breaker?
The TFK236150 is a legacy F-frame circuit breaker. It is primarily used to maintain or expand existing GE electrical infrastructure rather than for new installations.
