ABB / General Electric THQL2150 Miniature Circuit Breaker

This model is engineered for GE PowerMark Gold, GE PowerMark Plus, and the newer ABB ReliaHome load centers. It is not UL classified for other panelboards.

THQL breakers are standard full-size units measuring 1 inch per pole. THQP breakers are space-saving, half-inch models. The THQL2150 takes up two full 1-inch slots and cannot be replaced by a THQP equivalent unless the panel bus specifically supports half-inch twin breakers.

No. Following ABB's acquisition of GE Industrial Solutions, GE residential products are transitioning to the ABB ReliaHome brand. A THQL2150 bearing either the GE or ABB logo is the exact same component and remains fully interchangeable.

A 50A, 240V circuit is commonly specified for residential electric ranges, large hot tubs, EV charging stations, and subpanels. Always verify the specific overcurrent protection requirements of the connected load.

Yes, it carries an HACR rating, making it compliant for use with heating, air conditioning, and refrigeration equipment that requires 50A overcurrent protection.

This 2-pole unit requires two adjacent 1-inch spaces, occupying a total of 2 inches on the load center bus bar.

Yes, the built-in box lugs are rated for both copper and aluminum conductors within the 8 to 3 AWG range. When installing aluminum wiring, an approved antioxidant joint compound is recommended per standard trade practices.

No. It is not UL classified for installation in panels manufactured by Square D, Eaton, Siemens, or other brands. Installing this breaker in an unapproved panel violates the National Electrical Code and voids the safety listing.
