Product FAQs
5 answersWhat panelboards are compatible with the TEYL1045B?
This bolt-on breaker is designed exclusively for GE A-Series lighting panelboards, including AE, AS, AQU, and AEU types configured for TEY-frame branch breakers.
Can I use the TEYL1045B to replace a standard TEY or TEYF breaker?
Yes, the TEYL1045B shares the same physical dimensions and mounting footprint as TEY, TEYF, TEYD, and TEYH breakers. It can be used as a direct upgrade in A-Series panelboards where a higher 65kAIC interrupting rating is required.
What does the "L" in the TEYL1045B catalog number indicate?
The "L" designates the highest interrupting capacity tier within the GE TEY family. While standard TEY breakers are rated at 14kAIC at 277VAC, the TEYL series provides a 65kAIC rating at 277VAC for high-fault applications.
What does the "B" suffix mean on this circuit breaker?
The "B" suffix indicates that the breaker includes factory-installed load-side lugs. The line side bolts directly to the A-Series panelboard bus, while the load lug accepts 10-4 AWG copper or aluminum wire.
Can the TEYL1045B be mounted on a standard DIN rail?
No, this is a bolt-on molded case circuit breaker. It must be bolted directly to the interior bus of a compatible GE A-Series panelboard and cannot be mounted on a DIN rail.
