Square D QOU3301042 is a 3-pole molded case circuit breaker from the QOU Series, designed for overcurrent protection in commercial and industrial power distribution systems. It is rated for 30A at 240V AC with a 10kA interrupting capacity, utilizing a thermal-magnetic trip mechanism for LI (Long-Time and Instantaneous) protection functions. This bolt-on breaker measures 4.05 in (102.87 mm) x 3 in (76.2 mm) x 2.95 in (74.93 mm) and weighs 1.41 lb, accepting wire sizes from AWG 14 to AWG 2 in aluminum or copper. Manufactured by Schneider Electric in Mexico, it complies with industry standards for molded case circuit breakers and is suitable for 3-phase applications in panelboards and load centers.
