Product FAQs
5 answersWhich panelboards are compatible with the TEYH1025B breaker?
This bolt-on breaker is designed specifically for use in GE A-Series lighting panelboards. It mounts directly to the panelboard bus using a secure bolt-on connection.
What is the difference between the standard TEY1025B and the TEYH1025B?
The H in the TEYH1025B part number indicates a higher interrupting rating. While a standard 1-pole TEY breaker is typically rated for 14kAIC at 277VAC, the TEYH series provides a 35kAIC rating at 277VAC for systems requiring higher fault current protection.
What wire sizes are accepted by the terminals on this 25A breaker?
The factory-installed lugs accept 14 to 10 AWG copper wire or 12 to 10 AWG aluminum wire. Always verify the specific torque requirements printed on the side of the breaker before terminating conductors.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions in 2018. As a result, Q-Line breakers like the TEYH1025B may arrive with either GE or ABB branding, but they are the exact same form, fit, and function.
Can the TEYH1025B be used in DC applications?
Yes, this thermal magnetic breaker is rated for DC applications up to 125VDC, providing an interrupting capacity of 10kAIC at that voltage.
