ABB / General Electric TEYL3030B Molded Case Circuit Breaker

This bolt-on branch breaker is designed specifically for GE A-Series lighting panelboards.

Yes. The TEYL series shares the exact same physical dimensions and bolt-on footprint as TEY, TEYF, TEYD, and TEYH breakers. This allows for an easy upgrade to a higher interrupting capacity without modifying the panel space.

When installed in a standard GE A-Series panelboard, it bolts directly to the bus. If you are using it in a standalone or unit-mount lug-to-lug application, a separate three-pole mounting base accessory is required.

Tightening torque for the factory-installed lugs depends on the wire gauge: 35 in-lb for 10 AWG, 40 in-lb for 8 AWG, and 45 in-lb for 6 to 4 AWG.

The LI designation indicates that the breaker provides Long-Time overload protection and Instantaneous short-circuit protection. Because it uses a fixed thermal-magnetic trip unit, these settings are factory calibrated and cannot be adjusted in the field.

ABB acquired GE Industrial Solutions, meaning the Q-Line TEYL series is now manufactured under the ABB umbrella. The breaker retains direct cross-compatibility with legacy GE installations.

Yes, this breaker carries an HACR rating. This means it has been tested and approved for protecting multi-motor heating, air conditioning, and refrigeration circuits.

The 65kA rating at 480/277VAC represents a high-interrupting capacity tier for the GE TEY family. It means the breaker can safely clear a fault current of up to 65,000 amps, making it suitable for industrial environments with high available fault currents.
