The ABB DPT63‑CB010 C63A 3P is an automatic dual‑power transfer switch (automatic change‑over switch) designed to provide reliable switching between a primary power source and a backup power source (such as a generator) in three‑phase electrical systems. It ensures continuity of power supply in critical applications by automatically transferring load when the mains supply fails and returning to the main source once it is restored. The device supports automatic, manual, and motorized operation and incorporates electrical and mechanical interlocks for safety. It is commonly used in industrial, commercial, and institutional installations where uninterrupted power is essential.
