Product FAQs
6 answersWhat panelboards are compatible with the TEYL1050B circuit breaker?
The TEYL1050B is designed for use in GE A-Series lighting panelboards, specifically bolt-on Type AS panels.
Is there a difference between the ABB TEYL1050B and the GE TEYL1050B?
No. ABB acquired GE Industrial Solutions, meaning the TEYL1050B is the exact same circuit breaker regardless of whether it is branded as ABB or General Electric.
Can the TEYL1050B circuit breaker be reverse fed?
Yes. Because this breaker does not have designated Line and Load markings, it is suitable for reverse feed applications when installed according to NEC guidelines and secured with an appropriate retaining bracket.
What does the L in the TEYL1050B part number signify?
In the GE TEY family of breakers, the L designates the highest interrupting capacity tier. It differentiates this breaker from lower-rated versions like the TEYD or TEYH by providing a 65kAIC rating at 277/480VAC.
Is the TEYL1050B rated for use with heating, air conditioning, and refrigeration (HACR) equipment?
Yes. Like most GE TEY-frame circuit breakers, the TEYL1050B carries an HACR rating. Because it is 50 amps or less, it is also UL listed for high-intensity discharge (HID) lighting applications.
Does the TEYL1050B provide ground fault or arc fault protection?
No. The TEYL1050B is a standard thermal-magnetic circuit breaker with fixed long-time and instantaneous trip functions. It does not include GFCI or AFCI protection.
