Q-line plug-in circuit interrupters are one-inch wide per pole, compact, thermal-magnetic devices designed for residential and commercial applications in ReliaHome™ load centers. These breakers feature quick-make / quick-break mechanisms and easy to spot trip indication to ensure safety and reliability. Ground fault circuit interrupter (GFCI) provides protection against overloads, short circuits, and ground faults. The GFCIs detect low levels of electrical current leakage (ground faults), and acts quickly to shut off power, with a purpose of preventing serious shock. The THQL1115GFT2 circuit interrupter is a 1 pole breaker rated at 15 Amps, with an interrupting rating of 10kAIC, and a voltage rating of 120Vac
