The Square D QO120VHCAFI is a single-pole combination arc fault circuit interrupter (CAFCI) designed to provide enhanced protection against both parallel and series arc faults in residential and light commercial branch circuits. It is rated for 120V AC, 20A operation and features a high interrupting capacity of 22kA, housed within a compact plug-in design measuring 121 mm H x 19 mm W x 74 mm D (4.8 in x 0.7 in x 2.9 in) and weighing 0.56 lb. This thermal-magnetic breaker with long-time and instantaneous trip functions is constructed for use in QO load centers and NQ panelboards, accepting copper or aluminum wire from 14 to 8 AWG via its pressure plate terminals, and it operates reliably within a temperature range of -25°C to 70°C (-13°F to 158°F). The device is CSA Certified and UL Listed, ensuring compliance with North American safety standards for circuit protection in applications requiring advanced arc fault detection.
