ABB / General Electric TEYH1050B Miniature Circuit Breaker

This breaker is specifically designed to bolt directly onto the bus of GE A-Series lighting panelboards. It is not compatible with standard GE residential load centers, such as the Powermark Gold series, which require plug-on Q-Line breakers.

The H designates the high-interrupting capacity tier of the TEY family. While a standard TEY breaker is rated for 14kAIC at 277VAC, the TEYH1050B provides a 35kAIC rating at the same voltage. Other tiers in this family include TEYF (18kAIC), TEYD (25kAIC), and TEYL (65kAIC).

Yes. Although it is manufactured as a bolt-on breaker for A-Series panelboards, it can be converted for unit-mount or lug-to-lug applications by installing it on a compatible GE TEY mounting base accessory.

Yes, this thermal-magnetic breaker is rated for 125VDC with a 10kA interrupting capacity, allowing it to be used in compatible DC control, battery, or solar applications.

The breaker includes factory-installed load lugs that accept either copper or aluminum conductors ranging from 10 AWG to 4 AWG. Always verify that your chosen wire size is appropriately rated for the 50A load per the National Electrical Code (NEC).

No, this miniature circuit breaker features a fixed thermal-magnetic trip unit. The long-time and instantaneous trip functions are factory set for 50 amps and cannot be adjusted in the field.

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