The Square D QOU1101021 is a 1-pole molded case circuit breaker from the QOU Series, designed to provide overcurrent protection for branch circuits. It operates at 120V with a 10A current rating and a 10kA interrupting capacity, utilizing a thermal-magnetic trip mechanism for long-time and instantaneous fault response. This bolt-on breaker measures 4.05 in (102.87 mm) x 1.5 in (38.1 mm) x 2.95 in (74.93 mm) and weighs 0.66 lb, accepting wire sizes from AWG 14 to AWG 2 in aluminum or copper. It is rated for single-phase operation within a temperature range of -13 to 158 °F (-25 to 70 °C). Typical applications include industrial control panels and lighting circuits requiring reliable, compact circuit protection.
