Product Overview
The DW17-1900 frame circuit breaker is a high-performance power distribution protection device designed for 50Hz AC networks with 380V rated voltage. Featuring fixed horizontal mounting and motor-driven quick-operating mechanism, it covers 1250A/1000A current ratings with 3P configuration. Its modular construction ensures easy maintenance, while draw-out version enables rapid replacement. The breaker provides selective protection through long-time overload delay and short-time short-circuit delay functions, meeting reliability requirements of power systems. 71527
Key Features
This breaker demonstrates multiple technical strengths: 1) Motor energy-storage operation with AC380V control voltage ensures fast closing with low consumption; 2) Intelligent trip unit records fault currents and operation time for diagnostics; 3) High-breaking capacity design (1900A frame) with arc-extinguishing system handles major short-circuits; 4) Front/rear wiring options adapt to various panel layouts. The compact structure minimizes arcing distance, optimizing cabinet space utilization. Operating temperature ranges from -5℃ to +40℃ with ≤90% humidity tolerance at 25℃. 62026
Typical Applications
Ideal for industrial power systems including substations, power plants and heavy manufacturing facilities. The 1250A version serves motor protection while 1900A frame protects main distribution lines. In steel, cement and chemical industries, it safeguards transformers and rectifiers against overload/short-circuit faults. Draw-out version supports hot-swap maintenance to minimize downtime. 11215
