Product FAQs
7 answersWhat equipment is compatible with the TFJ236250 circuit breaker?
This F-Frame breaker is designed for installation in GE A-Series panelboards, Spectra Series panelboards, switchboards, and motor control centers.
Can the TFJ236250 be used to replace older GE F-Frame breakers?
Yes, as part of the legacy GE F-Frame family, the TFJ236250 can serve as a direct replacement for older or obsolete models with the same physical footprint, including older SF250 series breakers.
What wire sizes and materials are accepted by the factory lugs on this breaker?
The standard lugs on the TFJ236250 accept 250 kcmil to 300 kcmil copper (Cu) wire only. Aluminum wiring is not supported with the factory-installed terminal configuration.
What does the LI trip function code indicate for this breaker?
The LI designation means the thermal-magnetic trip unit provides Long-Time (L) protection for sustained overloads and Instantaneous (I) protection for immediate tripping during severe short circuits.
Are the trip settings on the TFJ236250 adjustable?
This breaker features a thermal-magnetic trip unit with a fixed thermal element for overload protection and an adjustable magnetic element, allowing electricians to fine-tune the instantaneous short-circuit response.
Is this breaker suitable for direct current (DC) applications?
Yes, in addition to standard AC systems, the TFJ236250 is rated for DC applications up to 500VDC, making it viable for industrial DC control circuits and specialized distribution systems.
How is the TFJ236250 secured within a panelboard?
It utilizes a bolt-on mounting style, which requires bolting the breaker directly to the panelboard bus. This provides a secure, low-resistance connection that is highly resistant to mechanical vibration.
