Authentic ABB / General Electric THHQL1120AF – 20A AFCI Miniature Circuit Breaker

Providing essential branch and feeder arc-fault mitigation, this 20A single-pole breaker helps maintain compliance in older installations. It utilizes a standard pigtail neutral wire and delivers a 22kAIC interrupting capacity at 120/240VAC. Installation is supported across GE PowerMark Gold load centers and AQ Lighting panelboards. Note that this specific model has been superseded by the THHQL1120AF2 for combination AFCI needs. Thermal-magnetic trip technology ensures reliable defense.
