Overview

The ABB THQL1120AF2 is a 1-pole, 20 Amp Combination Arc Fault Circuit Interrupter (AFCI) breaker designed for residential and light commercial applications. Part of ABB's Q Line series, this breaker meets current NEC standards and provides advanced protection against electrical fires caused by parallel and series arcs, such as those resulting from damaged wire insulation or frayed extension cords. The THQL1120AF2 features a compact, one-inch-wide-per-pole design, maximizing panel space efficiency while ensuring reliable performance. Key specifications include a 10 kAIC interrupting rating at 120/240V, a pig-tail neutral connection, and a non-interchangeable trip style for enhanced safety. The breaker operates at 120 Vac or 120/240 Vac system voltages and is suitable for reverse feed applications. It includes a quick-make/quick-break mechanism for reliable switching and common trip bars to ensure simultaneous disconnection in multi-pole configurations. Trip indications are designed for easy visibility, enabling rapid fault identification and reducing downtime. The THQL1120AF2 is classified under UL File #E11592 and includes special markings such as HACR and SWD. Its plug-in design ensures straightforward installation into compatible electrical panels, making it an ideal choice for modern electrical systems requiring compliance with current safety codes. The breaker's fixed long-time and instantaneous settings provide consistent protection without the need for adjustable parameters, simplifying installation and maintenance. Applications include residential branch circuits, light commercial panels, and systems where arc fault protection is mandated by code.
