ABB / General Electric TEYH2070B Miniature Circuit Breaker

This bolt-on breaker is designed exclusively for GE A-Series lighting panelboards. It bolts directly to the copper or aluminum bus of the panel interior and cannot be used in standard load centers.

The 'H' in the catalog number designates a high interrupting capacity. While a standard TEY breaker is typically rated for 14kAIC at 480/277V, the TEYH2070B provides 35kAIC at the same voltage. Both share the exact same physical dimensions and bolt-on mounting style.

No. Despite its compact size, this is a bolt-on molded case circuit breaker intended for direct bus connection in A-Series panelboards. It does not feature DIN rail mounting clips.

Yes, it carries a DC rating of 10kAIC at 250VDC. This makes it suitable for specific industrial DC control circuits or battery backup systems requiring a 70A 2-pole disconnect.

The factory-installed lugs accept both copper (Cu) and aluminum (Al) conductors ranging from 4 AWG to 1/0 AWG. Ensure proper application of joint compound if utilizing aluminum wiring.

Yes, if your fault current calculations require a higher interrupting rating, the TEYH2070B will physically fit in the same A-Series panel space as a standard TEY or TEYF breaker of the same pole configuration.

No, this model features standard thermal-magnetic trip functions (Long-Time and Instantaneous) for overload and short-circuit protection. It does not provide GFCI or AFCI capabilities.
