QO arc-fault circuit interrupters (AFCI) quickly detects a wide range of arc-fault conditions, recognizes the nature and specific wave-form of an arc fault and trips the circuit breaker. Traditional circuit breakers and fuses are designed to detect overloads and short circuits. Arc-fault circuit breakers are designed to detect overloads, short circuits and arc faults.

Square D™ Arc Fault Circuit Breaker, 120 VAC, 20 A, 60 Hz Frequency, 10 kA Interrupt, QO/100 A Frame, Thermal/Magnetic Trip, 1 Pole, 1 ph, Pressure Plate Connection, 12 to 8 AWG, 14 to 8 AWG Wire, Plug-On Mounting, 40 deg C, 4.75 in H x 0.75 in W x 2.9 in D Dimensions

• An arc-fault circuit breaker opens the circuit and stops the arcing and high intensity heat before a fire is likely to ignite
• Have special microprocessor-based arc identification to differentiate necessary operational arcs (associated with loads such as electric motors, switches and receptacles) from actual arc faults which can cause damage and fires
• Differentiate true arc faults from chopped wave-forms associated with switched-mode power supplies on electrical appliances, computers and lamp dimmers
• 14 - 8 AWG copper, 12 - 8 AWG aluminum
• K-Curve trip
• Combination ARC fault
