ABB / General Electric THQL21110 Miniature Circuit Breaker

ABB acquired GE Industrial Solutions. As a result, GE Q-Line breakers like the THQL21110 are transitioning to ABB branding. They are fully interchangeable and compatible with both legacy GE PowerMark Gold and new ABB ReliaHome load centers.

The THQL21110 has a standard interrupting rating of 10kAIC at 120/240VAC. The THHQL21110 is the high-interrupting version of the same 110A breaker, rated for 22kAIC. Both share the same physical dimensions and plug-in mounting style.

This 2-pole THQL breaker requires two standard 1-inch spaces in a compatible load center or panelboard.

Yes, GE THQL series circuit breakers are UL listed as HACR type, making them suitable for heating, air conditioning, and refrigeration motor loads.

THQP breakers are 1/2-inch wide space-saving versions, but they are only available up to 50 amps. For a 110A circuit, you must use a full-size 1-inch per pole THQL breaker like the THQL21110.

No, the THQL21110 is a standard thermal-magnetic circuit breaker. It provides long-time overload and instantaneous short-circuit protection, but does not include arc-fault or ground-fault circuitry.

No, this breaker features fixed thermal and fixed magnetic trip settings. It does not support field adjustments for the long-time or instantaneous trip functions.
