Description

Providing high-interrupting capacity for demanding loads, the GE THED124030 handles up to 25kAIC at 480VAC. This 2-pole, 30A breaker utilizes fixed thermal-magnetic trip technology for accurate overload and short-circuit response. Designed for bolt-on installation, it mounts into GE A-Series and Spectra Series panelboards. Facilities can use this E-Frame unit to replace standard TED124030 breakers when higher fault ratings are required. The device includes factory-installed load lugs.

Product FAQs

6 answers
Which panelboards are compatible with the THED124030 circuit breaker?

This E-frame breaker is designed for bolt-on installation in GE A-Series and GE Spectra Series panelboards.

What wire sizes are accepted by the lugs on the THED124030?

The factory-installed lugs accept 14 to 3 AWG copper wire or 12 to 1 AWG aluminum wire.

Can the THED124030 be used in direct current (DC) systems?

Yes, this thermal-magnetic breaker is rated for up to 250VDC with a 10kA interrupting capacity.

What is the difference between a TED124030 and a THED124030?

Both share the same physical E150 frame dimensions and mount into the same panelboards. However, the THED124030 is the high-interrupting tier, offering a 25kAIC rating at 480VAC compared to the standard TED version.

Is the THED124030 suitable for reverse feed applications?

Yes, GE E150 frame breakers, including the THED series, are suitable for reverse feed installations.

What does the WL suffix mean if my old breaker is marked THED124030WL?

The WL suffix simply indicates that the breaker was factory-supplied with copper and aluminum line and load lugs. The base THED124030 breaker is the exact same unit.

    Breakers and more....

    I believe I have left several reviews for SuperBreakers, all with praise on the quality of their product, their friendly and knowledgeable staff, and superb pricing, and this review is no different. I have yet to be let down or disappointed by their products or team members. Top notch all around! Once you use them, you will see how valuable a resource they really are to have in almost any situation that requires breakers or any type of motor control or switch gear.
