Description

Designed for standalone and switchboard applications, the TJD432250WL is a 3-pole, 250A molded case circuit breaker with a unit mount configuration. The WL suffix indicates the inclusion of both line and load lugs, making it ideal for feed-thru setups in GE J-Frame enclosures. Delivering 22kAIC of interrupting capacity at 240VAC, it utilizes a non-interchangeable thermal magnetic trip unit with Long-Time and Instantaneous (LI) protection functions for dependable industrial performance.

Product FAQs

8 answers
What enclosures are compatible with the TJD432250WL circuit breaker?

This feed-thru breaker is designed for installation in GE J-Frame enclosures and compatible industrial switchboards.

Are terminal lugs included with the TJD432250WL?

Yes, the WL suffix in the catalog number indicates that both line and load side lugs are factory installed. The lugs accept either one 6 AWG to 600 kcmil wire or two 2/0 AWG to 250 kcmil wires, and are rated for copper or aluminum conductors.

Is the TJD432250WL rated for direct current (DC) systems?

Yes, in addition to its 240VAC rating, this breaker is rated for use on 250VDC systems with a maximum interrupting capacity of 20kA.

Can I adjust the trip settings on the TJD432250WL?

No, this breaker features a fixed thermal and fixed magnetic trip unit. The Long-Time and Instantaneous (LI) protection parameters are factory set and cannot be modified in the field.

Why might my TJD432250WL arrive with an ABB label instead of GE?

ABB acquired GE Industrial Solutions in 2018. As a result, newly manufactured TJD432250WL breakers may feature ABB branding. The physical dimensions, fit, and internal components remain identical to the legacy GE versions.

How is the TJD432250WL mounted in a panel?

It features a unit mount, feed-thru design. It bolts directly to the enclosure or mounting pan rather than plugging onto a busbar, making it suitable for standalone enclosures and switchboards.

What type of fault protection does the TJD432250WL provide?

It uses a thermal magnetic trip mechanism to protect electrical circuits. The thermal element responds to sustained overloads, while the magnetic element trips instantaneously during high-current short circuits.

Is the trip unit on the TJD432250WL interchangeable?

No, the thermal magnetic trip unit is fixed and non-interchangeable. If your application requires a different amperage rating or trip characteristic, you must replace the entire circuit breaker.
