Description
An ideal solution for industrial facilities, the GE TFJ236070 is a 70A, three-pole molded case circuit breaker. This F-Frame device is rated for 600VAC and 500VDC, offering versatile thermal-magnetic protection with an adjustable instantaneous trip. It is designed to mount into legacy GE A-Series panels, Spectra panelboards, and commercial switchboards. For facilities looking to modernize, this legacy breaker can be replaced by the ABB Tmax XT4 series when paired with a retrofit kit.Specifications

Product FAQs
6 answersWhich panelboards are compatible with the TFJ236070 circuit breaker?
This F-Frame breaker is designed for bolt-on installation in GE A-Series panelboards, GE Spectra panelboards, and compatible switchboards. Verify your specific interior bus structure accepts TFJ frame types before installation.
What does the adjustable magnetic trip function allow on this breaker?
While the thermal overload protection is fixed at 70A, the adjustable magnetic trip allows electricians to set the instantaneous short-circuit response threshold. This helps coordinate with downstream devices and prevents nuisance tripping from motor inrush currents.
What type of wire can be used with the standard lugs on the TFJ236070?
The factory lugs accommodate both copper and aluminum conductors ranging from 4 AWG to 300 kcmil. Always apply an approved oxide inhibitor when terminating aluminum wiring to prevent galvanic corrosion.
Is the TFJ236070 suitable for direct current (DC) systems?
Yes, this thermal magnetic breaker is rated for DC use. It provides a 10kA interrupting capacity at both 250VDC and 500VDC, making it suitable for specific industrial DC control panels or battery systems.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions in 2018. Legacy GE molded case circuit breakers, including the TFJ F-Frame series, are now manufactured and supported under the combined ABB / General Electric brand.
Can this breaker be applied on 480V and 600V AC systems?
Yes, it is fully rated for high-voltage AC applications. It provides 22kAIC at 480VAC and 18kAIC at 600VAC, which meets the fault current requirements for many commercial and industrial distribution systems.
