Product FAQs
7 answersWhich panelboards are compatible with the TEYH3045B circuit breaker?
The TEYH3045B is designed for use in GE A-Series lighting panelboards, including AS, AE, AD, and AQ types that accept bolt-on TEY-frame breakers.
What is the difference between a standard TEY and the TEYH3045B?
The H in the TEYH prefix indicates a higher interrupting capacity. While standard TEY breakers are rated at 14kAIC at 480Y/277V, the TEYH3045B is rated for 35kAIC at 480Y/277V.
How does the TEYH3045B mount into the panelboard?
This breaker bolts directly to the bus of GE A-Series panelboards. It cannot be used in load centers that require plug-on or Q-Line residential breakers, despite being part of the broader Q-Line family.
Why is this breaker listed as both ABB and General Electric?
ABB acquired GE Industrial Solutions in 2018. As a result, TEY-frame breakers like the TEYH3045B may arrive with either GE or ABB branding, but they are the exact same form, fit, and function.
Is the TEYH3045B suitable for reverse feeding?
Yes, TEY-frame breakers are suitable for reverse feed applications.
Is the TEYH3045B HACR rated?
Yes, TEY-frame breakers are UL listed for HACR (Heating, Air Conditioning, and Refrigeration) applications.
Can the trip settings on the TEYH3045B be adjusted in the field?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time (overload) and instantaneous (short-circuit) trip functions are factory-calibrated and non-interchangeable.
