Product FAQs
5 answersWhich panelboards are compatible with the TEYH3040B circuit breaker?
This breaker is designed specifically for use in GE A-Series lighting panelboards. It features a bolt-on mounting style that connects directly to the panelboard bus.
What is the difference between a standard TEY3040B and the TEYH3040B?
The 'H' in the TEYH3040B catalog number indicates a higher interrupting rating. While a standard TEY breaker is rated for 14kAIC at 480Y/277VAC, the TEYH series provides a 35kAIC rating at the same voltage.
What type of wire can be used with the lugs on this breaker?
The factory-installed lugs accept both copper (Cu) and aluminum (Al) conductors ranging from 10 AWG to 4 AWG.
Why might my TEYH3040B arrive with ABB branding instead of General Electric?
ABB acquired GE Industrial Solutions in 2018. As a result, Q-Line breakers like the TEYH3040B are transitioning to ABB branding. The physical dimensions, mounting, and electrical specifications remain identical regardless of the logo on the label.
Can the trip settings on the TEYH3040B be adjusted in the field?
No, this breaker features a fixed thermal magnetic trip unit. Both the long-time (thermal) and instantaneous (magnetic) trip functions are factory set and cannot be modified.
