Schneider Electric QOU3201200 Molded Case Circuit Breaker

Schneider Electric's QOU3201200 is a 240 V, 20 A three‑pole miniature molded‑case circuit breaker designed to protect 3‑phase distribution circuits in commercial and industrial panels. Part of the Square D QOU family, this unit includes an auxiliary contact for signaling and uses a thermal‑magnetic trip to interrupt the circuit on overload or short circuit. It is rated for up to 10 kA of interrupting capacity at 240 VAC (and 5 kA at 48 VDC), making it suitable for 3‑phase feeders and motor circuits in typical installations. The QOU3201200 is designed to be installed in standard electrical enclosures and integrates with other Square D components for coordinated protection. This three‑pole unit is specified for 240 VAC operation with a 20 A rating, matching common commercial and industrial electrical designs that require reliable overcurrent protection with an auxiliary signaling interface. The part number is QOU3201200 and it carries Schneider Electric's Square D branding for compatibility with QOU-frame products.
