Product FAQs
7 answersWhat panelboards are compatible with the TEYF225 circuit breaker?
The TEYF225 is designed for use in GE A-Series lighting panelboards. It features a bolt-on mounting style that secures directly to the panelboard bus for commercial and industrial applications.
Can I install the TEYF225 in a standard residential Q-Line load center?
No. Although it is part of the Q-Line family, the TEYF225 is a bolt-on breaker designed specifically for commercial A-Series panelboards. It will not fit in plug-on residential load centers.
What is the difference between the GE TEY225 and the TEYF225?
Both are 2-pole, 25A bolt-on breakers for A-Series panels, but they have different interrupting ratings. The standard TEY225 is rated for 14kAIC at 480/277VAC, while the TEYF225 has a higher interrupting capacity of 18kAIC at 480/277VAC.
What wire sizes do the lugs on the TEYF225 accept?
The load side lugs on this breaker accept 14 AWG to 10 AWG copper or aluminum wire.
Can the TEYF225 be used in DC voltage applications?
Yes, this breaker is rated for up to 250VDC with an interrupting capacity of 10kAIC, making it suitable for specific direct current control and distribution circuits.
What does the 480/277VAC slash rating mean for this breaker?
A slash rating indicates the breaker is intended for use on a solidly grounded wye system where the line-to-ground voltage does not exceed 277V, and the line-to-line voltage does not exceed 480V.
Does the TEYF225 provide ground fault or arc fault protection?
No, this is a standard thermal-magnetic breaker providing only long-time overload and instantaneous short-circuit protection. It does not include GFCI or AFCI circuitry.
