ABB THQL1115PDFA - 15A, AFCI Arc-Fault Circuit Breaker

Engineered for demanding distribution environments, the ABB THQL1115PDFA delivers dependable overcurrent protection with integrated arc-fault sensing in a compact 15A package. This AFCI arc-fault circuit breaker is designed to secure panelboards, switchboards, control panels, and OEM equipment where arcing poses a fire risk without compromising performance.

Arc-fault protection matters because it detects dangerous electrical arcing, a common source of insulation damage and fires in both new builds and retrofits. The THQL1115PDFA combines precise arc-detection with reliable overcurrent interruption, helping you maintain safer, more compliant power distribution in busy industrial and commercial environments.

• Current rating: 15A, enabling protection for typical control circuits, lighting feeders, and small motor loads within commercial and light-industrial panels.
• AFCI technology: Detects both series and parallel arc faults, interrupting the circuit quickly to reduce fire risk and equipment damage.
• Application versatility: Suitable for panelboards, switchboards, control panels, and OEM equipment—especially in motor control centers and distribution panels where reliable protection is essential.
• Industry-ready protection: Designed to perform in environments where dependable operation and safety are critical, helping to safeguard personnel and downstream equipment.

Ideal use cases

Use the ABB THQL1115PDFA to upgrade or specify protective solutions in manufacturing lines, commercial building automation, and OEM equipment assemblies. It’s an excellent choice when arc-fault protection must be integrated into larger distribution schemes or embedded in control architectures that demand robust, continuous protection without frequent nuisance trips.
