Abb THQB1115AF2 Arc Fault Breaker 15A 1P 120/240V

Product Description

The ABB THQB1115AF2 is a bolt-in arc fault circuit interrupter (AFCI) miniature circuit breaker rated for 15 amps at 120/240 volts on a single pole. Designed to detect and interrupt arc faults that standard overcurrent breakers cannot, the THQB1115AF2 provides a critical layer of fire protection in residential and light commercial electrical systems. With a 10 kA interrupting rating, it handles fault currents common in branch circuit applications. Licensed electricians install this breaker as part of NEC-required arc fault protection in bedrooms, living areas, and other specified locations.

The THQB1115AF2 is suited for use in bolt-in panelboards and load centers that accept THQB-series breakers. It is a single-pole, 15-amp AFCI breaker appropriate for 120/240-volt branch circuits requiring arc fault protection per current National Electrical Code requirements. Typical applications include new construction wiring and retrofit upgrades where AFCI protection is mandated by code.

Key Features

• Arc fault circuit interrupter (AFCI) technology for fire hazard reduction
• 15 amp continuous current rating
• 10 kA interrupting capacity for reliable fault clearing
• Single-pole design for standard branch circuit protection
• 120/240 volt rated for residential and light commercial use
• Bolt-in mounting for secure installation in compatible panelboards

Compatibility

Designed as a bolt-in replacement or new-install AFCI breaker for panelboards and load centers that accept THQB-series miniature circuit breakers.

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 absence of voltage before handling any breakers or conductors. Confirm the host panelboard accepts THQB bolt-in breakers before installation. Do not exceed the breaker's rated ampacity with connected loads.
