Description
Belonging to the legacy J-Frame family, the GE TJD422300 is a 2-pole, 300A molded case circuit breaker. It utilizes a fixed thermal magnetic trip unit to deliver dependable LI protection. This bolt-on breaker mounts into GE A-Series and Spectra panelboards. It substitutes the TJJ422300 and can be replaced by the Tmax XT5 series using a retrofit kit. Rated for 240VAC, the unit provides a 22kAIC interrupt capacity. It features a common trip mechanism and load-side lugs.Specifications

Product FAQs
6 answersWhich panelboards are compatible with the TJD422300 circuit breaker?
This bolt-on breaker is designed specifically for installation in legacy GE A-Series and GE Spectra panelboards.
Can the TJD422300 be reverse fed?
Yes, this thermal-magnetic molded case circuit breaker is suitable for reverse feed applications.
What is the modern replacement for the legacy GE TJD422300?
The GE J-Frame series has been phased out. The ABB Tmax XT5 series is the official modern replacement, though a retrofit kit is required to install it in existing GE panelboards.
Why might my TJD422300 breaker have ABB branding instead of General Electric?
ABB acquired GE Industrial Solutions in 2018. Depending on the production batch, the breaker may feature either ABB or GE branding, but the physical dimensions, fit, and function are identical.
Which lug kit is used for terminating wires on this breaker?
The TCAL43 lug kit is standard for this frame, accommodating either one 6 AWG to 600 kcmil wire or two 2/0 AWG to 250 kcmil copper or aluminum wires per pole.
What does the TJD prefix signify in the part number?
It indicates a GE J-Frame molded case circuit breaker equipped with a non-interchangeable thermal-magnetic trip unit, designed for standard interrupting capacity at 240V.
