ABB / General Electric TEB122015 Molded Case Circuit Breaker

No. The TEB122015 is a bolt-on molded case circuit breaker designed specifically for commercial GE A-Series and Spectra Series panelboards. Residential GE PowerMark load centers require plug-on Q-Line breakers, such as the THQL series.

Following ABB acquiring GE Industrial Solutions, this breaker is now manufactured under the ABB brand. A TEB122015 marked GE and one marked ABB are the exact same product, retaining the same physical dimensions, E-150 frame, and trip characteristics.

Yes. In addition to its 240VAC rating, this thermal-magnetic breaker carries a DC interrupting rating of 5kAIC at 125/250VDC, making it suitable for specific control circuits or battery backup systems.

TEB, TED, and THED breakers all share the GE E-150 frame and are physically interchangeable. However, they have different interrupting capacities and voltage ratings. You can only substitute a TED or THED if it meets or exceeds the required fault current rating for your specific panel and application.

The factory-installed lugs accept 14 AWG to 8 AWG copper or aluminum wire. When terminating the conductors, always use a calibrated torque wrench and follow the torque specifications printed on the breaker label to ensure a secure, code-compliant connection.

No. This breaker features a fixed thermal-magnetic trip unit with Long-Time and Instantaneous (LI) functions. Neither the thermal overload nor the instantaneous magnetic short-circuit trip points are field-adjustable.

Always verify that the power supply is completely de-energized before installing or servicing the breaker. Ensure the available fault current at the panel does not exceed the 10kAIC at 240V rating of the TEB122015 to prevent equipment failure during a short circuit.
