ABB / General Electric TEYD3080B Miniature Circuit Breaker

This bolt-on breaker is specifically designed for installation in GE A-Series lighting panelboards. It is not compatible with standard residential Q-Line load centers.

These breakers share the same physical frame and panel compatibility but differ in their interrupting capacity at 480Y/277V. The TEYD is rated at 25kAIC, the TEYH at 35kAIC, and the TEYL at 65kAIC.

No. The TEYD3080B has a slash voltage rating of 480Y/277V, meaning it is only approved for use on solidly grounded WYE systems where the voltage to ground does not exceed 277V. It cannot be installed on ungrounded or corner-grounded Delta systems.

Yes, GE TEY series breakers are suitable for reverse feeding, allowing them to be used as main breakers or back-fed branch devices in compatible panels.

As part of the GE Q-Line family, TEY frame breakers feature a 1-inch per pole width. This 3-pole breaker requires exactly 3 inches of continuous bus space in the panelboard.

Yes, the GE TEYXHT3 handle tie can be used to mechanically link the handles of adjacent TEYD, TEYH, and TEYL circuit breakers.

No. This is a standard thermal-magnetic breaker providing long-time and instantaneous (LI) trip functions for overcurrent and short-circuit protection. It does not provide GFCI, GFEP, or AFCI protection.
