Description
Engineered for heavy-duty power distribution, the GE TJD422400 is a 400A, two-pole molded case circuit breaker. It delivers reliable long-time and instantaneous protection for 240VAC commercial and industrial electrical systems. Designed as a bolt-on component, it fits seamlessly into legacy GE A-Series and Spectra panelboards. It acts as a direct substitute for the TJJ422400 and is officially replaced by the Tmax XT5 series. This J-Frame breaker features a 22 kAIC interrupt rating.Specifications

Product FAQs
7 answersWhich panelboards are compatible with the TJD422400 circuit breaker?
This J-Frame breaker is designed to bolt directly into legacy GE A-Series and GE Spectra panelboards.
Can the TJD422400 be used in direct current (DC) applications?
Yes, this breaker is rated for use in DC systems up to 250VDC, with a maximum interrupting capacity of 20kAIC at that voltage.
What wire sizes are accepted by the lugs on this 400A breaker?
The standard lugs accept either one wire from 6 AWG to 600 kcmil, or two wires from 2/0 AWG to 250 kcmil. They are compatible with both copper and aluminum conductors.
What does the LI trip function code mean on the TJD422400?
The LI designation indicates a thermal magnetic trip unit providing Long-Time (L) overload protection and Instantaneous (I) short-circuit protection. Both the thermal and magnetic trip points are fixed on this model.
Is the GE TJD422400 an obsolete circuit breaker?
The TJD series is a legacy General Electric J-Frame breaker. While GE industrial breaker lines were acquired by ABB, these legacy breakers are still utilized for maintaining existing A-Series and Spectra panelboards.
Can the TJD422400 replace a TJJ422400 circuit breaker?
Both are GE J-Frame breakers with identical physical dimensions and bolt-on mounting. However, the TJD has a standard interrupting capacity, while the TJJ has a higher interrupting rating. You must verify that the 22kAIC rating of the TJD422400 meets your system fault current requirements before substituting.
What is the modern ABB replacement for the legacy GE TJD422400?
The TJD422400 is officially replaced by the ABB Tmax XT5 series. Upgrading to the XT5 series may require retrofit hardware or panel modifications when installing into legacy GE enclosures.
