ABB / General Electric THED136025 Molded Case Circuit Breaker

This bolt-on breaker is designed specifically for GE A-Series and GE Spectra Series panelboards. It is also utilized in compatible GE motor control centers and switchboards that accept E150 line E-frame breakers.

The included lugs accept copper conductors ranging from 14 AWG to 3 AWG, and aluminum conductors from 12 AWG to 1 AWG. Ensure proper torque specifications are followed during installation.

To safely operate at its maximum 500VDC rating, all three poles of the breaker must be wired in series. For 250VDC systems, standard wiring configurations are permitted.

Both are 25A, 3-pole breakers within the GE E150 frame family. The THED136025 is the high-interrupting capacity version, rated for 25kA at 480VAC. The standard TED136025 is rated for 18kA at 480VAC. The THED model is an exact physical drop-in upgrade for the TED version.

Yes. Following ABB's acquisition of GE Industrial Solutions, these E-frame breakers are manufactured under the ABB / General Electric brand. They share the exact same physical dimensions, mounting hardware, and UL listings, making them fully interchangeable.

No. This breaker features a fixed thermal magnetic trip unit. Both the long-time (overload) and instantaneous (short circuit) protection functions are factory set and non-adjustable.

No. The THED136025 is UL listed exclusively for use in compatible GE enclosures, such as A-Series and Spectra Series panels. Installing it in a panelboard from a different manufacturer violates electrical codes and creates a severe safety hazard.
