Schneider Electric QOU380 U Molded Case Circuit Breaker

Schneider Electric's QOU380 U molded‑case circuit breaker is a three‑pole, 80‑amp unit‑mount MCCB designed for 240 VAC power distribution. In the Square D QOU family, it provides thermal‑magnetic overload protection with a 10 kA interrupt rating at 240 VAC, enabling reliable short‑circuit protection for feeders and branch circuits in commercial and light‑industrial panels. Its molded‑case construction and unit‑mount format support straightforward installation in standard distribution panels and panelboards, with the device engineered to interrupt all three phases simultaneously to guard against phase‑to‑phase faults and unbalanced loads in 3‑phase networks. Typical applications include protection of feeders to subpanels, motor circuits, and other 240 V equipment in commercial buildings, manufacturing facilities, and data‑center environments where compact, dependable protection is required. This Schneider Electric device embodies the QOU designation, reflecting its place in the QOU line of reliable miniature/molded‑case breakers known for clear trip characteristics and robust performance in everyday electrical distribution tasks.
