The Square D QO2020CP is a 20A, 1-pole molded case circuit breaker designed for overcurrent and short-circuit protection in residential and commercial power distribution systems. It operates at 120/240VAC with a 10kAIC rating and features a thermal-magnetic trip mechanism providing LI (Long-Time and Instantaneous) protection functions. This plug-in style breaker measures 3.2 in x 0.7 in x 2.9 in (82 mm x 19 mm x 74 mm), weighs 0.319 lb, and accepts copper or aluminum wire from AWG 14 to AWG 8. It is UL and CSA certified, complies with RoHS, REACh, and HACR standards, and operates within a temperature range of -13°F to 158°F (-25°C to 70°C). The QO2020CP is typically used in QO load centers and panelboards for lighting, appliance, and branch circuit protection in single-phase systems.
