THQB1115AF - 15Amp Circuit Breaker

THQB1115AF - 15 Amp Circuit Breaker

The THQB1115AF is a 15-amp, single-pole circuit breaker designed for use in Q-Line panelboards. This breaker combines standard overcurrent protection with Arc Fault Circuit Interrupter (AFCI) technology, helping you to protect branch circuits from overloads, short circuits, and potentially dangerous arc-fault conditions. Built with a bolt-on mounting design, the THQB1115AF provides a secure connection within the panel and is commonly used in residential and light-commercial electrical systems operating at 120 VAC. The breaker is HACR rated, making it suitable for applications involving heating, air conditioning, and refrigeration equipment. Its molded case construction helps protect internal components while supporting dependable operation over time. Whether you're replacing an existing breaker or completing a panel upgrade, the THQB1115AF is a practical choice for AFCI protection.
