ABB / General Electric THHQL1115DF Dual Function Miniature Circuit Breaker

This breaker is designed for use in GE PowerMark Gold Load Centers, GE A-Series Panelboards, and ABB ReliaHome Load Centers that accept full-size 1-inch THQL frame breakers.

No. The THHQL1115DF is a standard 1-inch wide THQL frame breaker. It will not fit into the half-inch spaces designed exclusively for thin THQP breakers.

This breaker features a pigtail neutral connection. The coiled white pigtail wire must be connected directly to the panel neutral bus bar, while the branch circuit neutral connects to the designated load neutral terminal on the breaker itself.

No. Dual function (AFCI/GFCI) breakers require a dedicated neutral for each circuit to function correctly. Using this breaker on a shared neutral (multi-wire branch circuit) will result in nuisance tripping.

It provides both Combination Arc Fault (AFCI) protection to mitigate electrical fire risks and Ground Fault (GFCI) protection for personnel safety against electrical shock, in addition to standard thermal-magnetic overload and short-circuit defense.

The HH prefix designates a higher interrupting rating of 22kAIC at 120V, compared to standard 10kAIC residential breakers which typically use a single H (such as THQL). This makes it suitable for systems with higher available fault currents.

Yes. Following ABB's acquisition of GE Industrial Solutions, these breakers are manufactured to the exact same specifications. Depending on the production date, the unit or packaging may be branded as either GE or ABB, but they are fully interchangeable.
