Product FAQs

7 answers
What panelboards are compatible with the TEYH1020B circuit breaker?

The TEYH1020B is a bolt-on breaker designed specifically for GE A-Series lighting panelboards, including AE and AS subtypes. It is not interchangeable with plug-on Q-Line breakers or other brands.

What does the H in the TEYH series designation mean?

The H indicates a high short-circuit interrupting tier within the GE TEY frame family. The TEYH1020B delivers 35kAIC at 277VAC and 65kAIC at 120/240VAC, offering greater fault protection than standard TEY (14kAIC) or TEYF (18kAIC) breakers.

Can the TEYH1020B be used as a direct replacement for a standard TEY1020B?

Yes. The TEYH1020B shares the exact same physical dimensions, 1-inch pole spacing, and bolt-on mounting configuration as the standard TEY1020B. It simply provides a higher interrupting capacity, making it a safe upgrade for existing installations.

Is the TEYH1020B rated for switching high-intensity discharge (HID) lighting?

Yes. This 20-amp breaker is UL listed as HID rated, meaning its thermal-magnetic trip unit is tested to safely handle the high inrush currents typical of high-intensity discharge lighting fixtures without nuisance tripping.

Can this breaker be used for switching standard fluorescent lighting loads?

Yes. The TEYH1020B carries an SWD (Switching Duty) rating, which permits it to be used as a regular switch for 120V or 277V fluorescent lighting circuits.

Is the TEYH1020B suitable for HVAC applications?

Yes. The breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires HACR-certified overcurrent protection.

Does the TEYH1020B require a separate mounting base?

When installed directly into a GE A-Series panelboard, the breaker bolts straight to the bus and requires no additional base. If you are using it in a standalone unit-mount or lug-to-lug application, a separate TEY3B mounting base accessory is required.
