Product FAQs
5 answersWhich panelboards are compatible with the TEYD1050B circuit breaker?
This breaker is designed for use in GE A-Series lighting panelboards. It features a bolt-on mounting style that connects directly to the bus within these specific panels.
How does the TEYD series differ from standard TEY breakers?
The TEYD series offers a higher interrupting capacity than the standard TEY line. While standard TEY breakers are rated for 14kAIC at 277VAC, the TEYD1050B provides a 25kAIC rating at 277VAC for systems requiring higher fault current protection.
What wire sizes and materials are accepted by the lugs on this 50A breaker?
The factory-installed lugs on the TEYD1050B accept both copper and aluminum wiring ranging from 10 AWG to 4 AWG.
Is this breaker manufactured by ABB or General Electric?
ABB acquired GE Industrial Solutions, so this breaker may be branded as either ABB or General Electric. The TEYD1050B catalog number and physical specifications remain identical regardless of the brand name printed on the label.
Does this breaker require a separate mounting base for installation?
When installed in a compatible GE A-Series panelboard, it bolts directly to the panel bus. However, if you are using it in a unit-mount or lug-to-lug application, a separate TEY mounting base is required.
