The Square D QO220HID is a 2-pole, 20A molded case circuit breaker designed for overcurrent and short-circuit protection in high intensity discharge (HID) lighting applications. It is rated for 120/240V AC, single-phase systems, with an AIC rating of 10kA at 240V, and features a thermal-magnetic trip mechanism providing long-time and instantaneous protection. The breaker measures 3.0 in (76 mm) in height, 1.5 in (38 mm) in width, and 2.9 in (74 mm) in depth, weighing 0.53 lb, with a plug-in connection and pressure plate terminals accepting AWG 14 to AWG 8 copper or aluminum wire. It is CSA certified and UL listed, compliant with industry standards for safety and performance. This breaker is intended for use in QO load centers and NQ panelboards, operating within a temperature range of -13 to 158 °F (-25 to 70 °C), making it suitable for industrial HID lighting circuits.
