Description
Providing essential overcurrent safety, the GE TJD432250 3-pole, 250A molded case circuit breaker utilizes a fixed thermal and adjustable magnetic trip unit to handle commercial loads. This bolt-on breaker mounts into GE A-Series panelboards, Spectra Series panels, and switchboards. It features load lugs only, as the line side bolts to the panel bus. It can be replaced by the Tmax XT4 using a retrofit kit. It delivers a 22kAIC interrupting rating at 240VAC for reliable performance.Specifications

Product FAQs
6 answersWhich panelboards are compatible with the TJD432250 breaker?
This J-frame breaker is designed for bolt-on installation in GE A-Series panelboards, GE Spectra Series panelboards, and GE switchboards. Verify your specific interior accepts J-frame dimensions before installation.
What wire sizes are accepted by the lugs on this breaker?
The standard lugs accept either a single conductor from 6 AWG to 600 kcmil, or dual conductors from 2/0 AWG to 250 kcmil. Both copper and aluminum wires are supported.
Is the TJD432250 suitable for direct current applications?
Yes, this breaker is rated for DC systems up to 250VDC, providing a 20kA interrupting capacity for those specific applications.
How do I adjust the trip settings on this thermal magnetic breaker?
The thermal element for long-time overload protection is fixed at 250 amps. However, the magnetic instantaneous trip is adjustable, allowing you to tune the short-circuit response based on your specific load requirements.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions. As a result, legacy GE molded case circuit breakers like the TJD series are now manufactured and supported under the ABB brand portfolio, but they remain direct replacements for existing GE installations.
What type of protection does the LI trip function provide?
The LI designation indicates Long-Time and Instantaneous protection. The thermal long-time function protects against sustained overloads, while the magnetic instantaneous function clears high-fault short circuits immediately to prevent equipment damage.
