ABB / General Electric TEYD1030B Miniature Circuit Breaker

The TEYD1030B is designed specifically for GE A-Series lighting panelboards. It bolts directly onto the panelboard bus and is fully compatible with Pro-Stock configurations.

The "D" in TEYD indicates a higher interrupting capacity tier. While it shares the exact same 1-inch wide physical footprint as a standard TEY breaker, the TEYD1030B provides an upgraded 25kAIC rating at 277VAC and 65kAIC at 120/240VAC.

Yes, the TEYD1030B is a direct physical replacement for the standard TEY1030B. It mounts in the same A-Series panelboard spaces but safely provides a higher short-circuit interrupting rating.

Yes, while primarily designed to bolt onto A-Series panelboards, the TEYD1030B can be adapted for unit-mount or lug-to-lug applications by using a separate GE bolt-on mounting base accessory.

Yes, this thermal-magnetic breaker is rated for 125VDC applications with a 10kAIC interrupting capacity, in addition to its standard AC voltage ratings.

No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time and instantaneous trip functions are factory-set and non-interchangeable to prevent accidental misapplication.

ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, the TEYD1030B may feature either ABB or GE branding, but the breaker remains identical in form, fit, and function.
