Schneider Electric QOU320U Circuit Breaker

Schneider Electric QOU320U is a 20-amp, three-pole miniature circuit breaker in the QOU family, rated for 240 VAC and designed to protect three-phase branch circuits in commercial and light-industrial panels. With a 10 kA interrupt rating, it provides robust overcurrent protection against short circuits and overloads, helping to safeguard wiring and equipment. As part of Square D's legacy line, the QOU320U offers reliable thermal-magnetic protection in compact form factors and is intended for use in compatible QOU enclosures or panelboards where three-phase 240-volt protection is needed. Key specifications include a 20 A current rating, 240 V AC voltage rating, and 3 poles, making it a straightforward replacement for similar 3P breakers in appropriate systems.
