CDW3 4000H 3200A3P Air Circuit Breaker is a high-performance power protection device specifically designed for AC380V distribution systems. Featuring modular construction and withdrawable rack design with horizontal rail installation, it facilitates equipment inspection and maintenance. With rated operational current up to 3200A, this product is ideal for medium-low voltage distribution applications in industrial plants, commercial buildings, and large-scale infrastructure projects.
Integrated with intelligent control unit, the breaker continuously monitors line voltage status. The under-voltage protection mechanism will automatically activate when system voltage drops below the preset AC380V threshold, precisely isolating faulty circuits to prevent equipment operation under abnormal voltage conditions. Its three-stage overcurrent protection combines optimized electromagnetic-thermal magnetic dual trip mechanism, enabling graded response to short-circuit and overload faults.
The breaker body adopts high-strength alloy frame structure with multi-layer arc chute design, ensuring reliable insulation performance during high short-circuit current interruption. The withdrawable base incorporates triple mechanical interlocks for safe switching among service, test, and disconnected positions. User-friendly interface includes switching status window and energy storage indicator for quick operational monitoring.
Optional communication protocol interfaces enable seamless integration with intelligent power management systems. Improved conductive circuit design reduces temperature rise by 15% compared to conventional products, effectively extending service life. With IP40 protection rating, it adapts to various challenging industrial environments. Compact layout through structural innovation saves 20% installation space versus comparable products.
