ABB / General Electric TEYF115 Miniature Circuit Breaker

This bolt-on breaker is designed specifically for GE A-Series lighting panelboards. It is not compatible with standard residential PowerMark Gold load centers, which require plug-on Q-Line breakers.

ABB acquired GE Industrial Solutions in 2018. As a result, TEYF series breakers are manufactured under both the GE and ABB brands. The form, fit, and function remain identical regardless of the logo on the label.

In the GE TEY breaker family, the letter designates the interrupting capacity tier at 277VAC. The TEYF series provides an 18kAIC rating, which is a step up from the standard TEY series rated at 14kAIC.

It utilizes a bolt-on mounting configuration. The breaker must be physically screwed into the panelboard busbar, providing a secure, vibration-resistant connection typical in commercial and industrial environments.

Yes, this thermal magnetic breaker is rated for use in DC circuits up to 125VDC, where it provides a 10kAIC interrupting rating.

Yes, the TEYF115 shares the same physical dimensions and bolt-on mounting as the standard TEY115. It can be used as a direct replacement or upgrade, offering a higher 18kAIC interrupting rating at 277VAC compared to the 14kAIC rating of the base TEY model.

The integrated load lugs accept copper or aluminum conductors ranging from 14 AWG to 10 AWG. Ensure you apply the correct torque specifications listed on the breaker label during installation.

It features a non-interchangeable thermal magnetic trip unit. The thermal component provides delayed protection against sustained overloads, while the magnetic component offers instantaneous protection against short circuits.

Yes, it is specifically designed for use on grounded 480Y/277VAC systems, making it a standard choice for commercial lighting and branch circuit distribution.
