ABB / General Electric TEYD3035B Miniature Circuit Breaker

This breaker is designed specifically for bolt-on installation in GE A-Series lighting panelboards (Type AS). It is not compatible with standard residential load centers or DIN rail systems.

The primary difference is the short-circuit interrupting rating at 480Y/277VAC. The TEYD is rated at 25kA, the TEYF at 18kA, and the TEYH at 35kA. They share the same physical footprint and panelboard compatibility.

Yes, in addition to its AC ratings, this breaker is UL listed for 250VDC applications with a maximum interrupting capacity of 10kA.

The factory-installed lugs accept 10 AWG to 4 AWG copper (Cu) or aluminum (Al) conductors. The required tightening torque depends on the wire gauge: 35 in-lb for 10 AWG, 40 in-lb for 8 AWG, and 45 in-lb for 6 AWG to 4 AWG conductors.

The bolt-on screw securing the breaker to the panelboard busbar should be tightened to 35 in-lb (3.95 Nm).

No, this breaker features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous trip functions cannot be adjusted in the field.

No, the TEYD3035B is a standard thermal-magnetic breaker providing long-time and instantaneous (LI) overload and short-circuit protection. It does not include AFCI or GFCI functionality.

Yes, it can replace standard TEY, TEYF, or other TEYD breakers of the same amperage and pole count, provided the 25kA interrupting rating meets or exceeds the available fault current of the system.
