Abb thql1115ax Afci Circuit Breaker 15A 1-pole 120/240V

Product Description

The ABB thql1115ax is a 15-amp, 1-pole Combination AFCI (Arc-Fault Circuit Interrupter) circuit breaker rated for 120/240 volts. It features a pigtail neutral connection and carries a 10kA interrupt rating. The Class A trip sensitivity is set at 5 milliamps, meeting NEC requirements for arc-fault protection in residential branch circuits. Licensed electricians install this breaker in load centers and panelboards where AFCI protection is required by code. UL listing confirms it has been independently tested and verified against applicable safety standards.

This breaker is suited for residential and light commercial applications where the National Electrical Code mandates AFCI protection — including bedrooms, living areas, kitchens, hallways, and other living spaces. The combination-type AFCI design addresses both parallel and series arc faults on the protected circuit. The pigtail neutral configuration allows installation in load centers that require a separate neutral conductor connection at the breaker itself rather than at the neutral bus.

Key Features

• Combination AFCI protection addresses both parallel and series arc faults
• 15-amp, 1-pole configuration for standard 120/240-volt branch circuits
• 10kA interrupting rating for reliable fault clearing
• Class A ground fault trip sensitivity at 5 milliamps
• Pigtail neutral connection for compatible load center installations
• UL listed for verified safety compliance

Compatibility

Designed as an OEM-style replacement for residential and light commercial panelboards accepting Q-Line style AFCI breakers with pigtail neutral termination.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the panel and verify the absence of voltage before beginning any work inside the load center. Confirm the target panelboard accepts Q-Line pigtail neutral breakers before installation. The neutral pigtail must be landed on the panel neutral bar as required by the breaker and panelboard instructions.
