QOU150 - 50 Amp Circuit Breaker

QOU150 - 50 Amp Circuit Breaker

Engineered by Schneider Electric, the QOU150 50A Circuit Breaker provides trusted over‑current protection for residential, commercial, and light industrial electrical systems. Designed to reliably safeguard panels and load centers, this single‑pole miniature circuit breaker supports both AC (120/240 V) and DC (up to 48 V) configurations. With a 10 kA interrupt capacity, it handles fault conditions with confidence—helping ensure your system stays protected from overloads and short bursts of electricity.

Key Features and Benefits

• Over‑current protection you can trust: Combines thermal and magnetic trip elements for both immediate and delayed response to surges—protecting wiring and equipment efficiently.
• High fault‑handling ability: Rated 10 kA interrupt capacity at 120/240 VAC, capable of managing significant fault currents without fail.
• Double‑duty use: Suitable for both AC and DC circuits, making it a flexible choice for electricians, panel builders, and OEM system integrators.
• Easy installation: Unit‑mount design with slotted box lugs on both line and load sides ensures straightforward wiring and secure connections.
• Built to last: Durable construction offers consistent performance even in tougher environments and with repeated use.
