CDW6I-4000N Air Circuit Breaker Product Introduction (English Version)
The CDW6I-4000N air circuit breaker is an intelligent protection device specifically engineered for industrial power systems, designed for controlling and protecting distribution networks in AC380V environments. With a modular construction and rated current capacity of 4000A, this product meets the operational demands of high-capacity power systems. Key functionalities include overload protection, instantaneous short-circuit interruption, and undervoltage protection (triggering at AC230V threshold), making it particularly suitable for industrial applications requiring continuous power supply such as pumping installations.
Integrating precision electromagnetic trip mechanisms with digital control technology, the breaker demonstrates exceptional breaking capacity, capable of extinguishing arcs within 20 milliseconds during short-circuit faults. The silver-alloy contact system combined with multi-chamber arc quenching design effectively reduces contact resistance while maintaining temperature rise within specified limits during full-load 4000A operation. Optimized transmission chain design ensures mechanical endurance exceeding 20,000 operational cycles.
Featuring IP40 protection rating and anti-corrosion coating on critical components, the unit adapts well to humid environments typical of pumping stations. The three-position energy-storage operating mechanism supports manual/electric mode switching, with standard mechanical interlocks preventing misoperation. The integrated monitoring unit provides digital display of current/voltage parameters, while the undervoltage protection threshold can be linearly adjusted (AC200-260V range) via front-panel controls for flexible field configuration.
This product finds extensive application in power distribution systems for water conservancy projects, industrial plants, and municipal infrastructure, particularly serving as critical protection for pump units and main power lines. Through optimized thermal management and low-power control circuitry, it achieves approximately 15% lower operational energy consumption compared to conventional models.
The design emphasizes ease of maintenance with front-accessible terminal connections and tool-free arc chute inspection ports. Optional communication modules enable remote monitoring of operational parameters through standard industrial protocols. Structural reinforcement at key stress points ensures vibration resistance up to 5Grms, maintaining reliable performance in dynamic industrial environments.
