Product FAQs
8 answersWhich panelboards are compatible with the TEYF350?
The TEYF350 is a bolt-on breaker designed specifically for use in GE A-Series Lighting Panelboards.
What is the difference between the standard TEY350 and the TEYF350?
Both breakers share the same physical dimensions and TEY frame, but the TEYF350 offers a higher interrupting rating. The TEYF350 is rated at 18kAIC at 480Y/277VAC, whereas the standard TEY350 is rated at 14kAIC. The TEYF350 can be used as a direct, upgraded replacement.
What are the lug torque specifications for the TEYF350?
The recommended lug tightening torque depends on the wire gauge used: 35 in-lb for 10 AWG, 40 in-lb for 8 AWG, and 45 in-lb for 6 to 4 AWG conductors.
Can I mount the TEYF350 on a standard DIN rail?
No, the TEYF350 is a bolt-on miniature circuit breaker. It must be bolted directly to the busbar of a compatible GE A-Series panelboard and does not support DIN rail mounting.
Can the TEYF350 be used in DC applications?
Yes, the TEYF350 is rated for DC applications and provides an interrupting capacity of 10kA at 250VDC.
Does the TEYF350 accept aluminum wiring?
Yes, the factory-installed lugs are rated for both copper (Cu) and aluminum (Al) conductors, accepting wire sizes from 10 AWG to 4 AWG.
Can I adjust the trip settings on the TEYF350?
No, the TEYF350 features a non-interchangeable, fixed thermal and fixed magnetic trip unit. The long-time and instantaneous trip functions cannot be adjusted in the field.
Is the TEYF350 suitable for HVAC equipment?
Yes, the TEYF350 is UL listed as HACR (Heating, Air Conditioning, and Refrigeration) rated, making it fully compliant for protecting HVAC circuits.
