Product FAQs
7 answersWhich panelboards are compatible with the TEY250 circuit breaker?
The TEY250 is designed specifically for GE A-Series lighting panelboards, including AE and AS panel interiors configured for 480Y/277V systems.
Can the TEY250 be installed on a 480V ungrounded delta system?
No. The TEY250 has a slash voltage rating of 480Y/277VAC. This means it is only approved for solidly grounded wye systems where the line-to-ground voltage does not exceed 277V. It is not suitable for 480V delta configurations.
Is the TEY250 suitable for direct current applications?
Yes. The thermal-magnetic trip unit in the TEY250 is rated for 250VDC systems and provides an interrupting capacity of 10kAIC at that voltage.
What are the terminal torque specifications for the TEY250?
Proper tightening torque depends on the installed wire size. Torque #10 AWG wire to 35 in-lb, #8 AWG wire to 40 in-lb, and #6 to #4 AWG wire to 45 in-lb.
How does the TEY250 connect to the panelboard?
The TEY250 is a bolt-on miniature circuit breaker. The line-side connects directly to the panel busbar using mounting bolts, which provides a secure connection that resists vibration in industrial settings.
Will an ABB-branded TEY250 fit my existing GE A-Series panel?
Yes. ABB acquired GE Industrial Solutions, and the TEY series is now manufactured under the ABB umbrella. An ABB-branded TEY250 has the exact same physical dimensions, UL listings, and mounting hardware as the legacy GE-branded version.
Does the TEY250 provide ground fault or arc fault protection?
No. The TEY250 is a standard thermal-magnetic circuit breaker featuring Long-Time and Instantaneous (LI) trip functions. It is designed for standard overload and short-circuit protection, not GFCI or AFCI applications.
