English Version:
The CDW3 2000N 1250A4P frame circuit breaker is an intelligent protection device designed for low-voltage distribution systems. Featuring drawer-type horizontal installation structure, it operates effectively in AC 230V to 380V environments. The product integrates optimized mechanical design with enhanced electrical performance to deliver reliable circuit switching control and system protection, meeting diversified requirements across industrial, commercial, and infrastructure applications.
Equipped with multi-level protection mechanisms, the breaker provides not only conventional overload and short-circuit protection but also advanced response capability for grid voltage fluctuations. Its undervoltage protection module activates promptly when detecting voltage below preset thresholds, preventing equipment malfunction caused by abnormal low voltage conditions. The interchangeable drawer-type design simplifies maintenance procedures, allowing module replacement through rail sliding mechanism to significantly reduce service downtime.
The modular architecture comprises three core components: main contact system, operating mechanism, and intelligent trip unit. The contact system utilizes high-conductivity alloy materials combined with segmented arc extinguishing technology to maintain stable arc control during high-current interruption. The operating mechanism has passed 200,000-cycle endurance tests, demonstrating reliable mechanical durability. The programmable trip unit enables on-site parameter adjustments for flexible protection setting according to actual operating conditions.
Surface treatment with multi-layer protective coating achieves IP40 protection grade, effectively preventing dust ingress. Main circuit terminals feature anti-corrosion plating technology to withstand high humidity and temperature variations. The compact cabinet layout design ensures compatibility with various distribution panel specifications, optimizing space utilization.
Typical applications include power distribution systems for industrial production lines, main power supply circuits in commercial complexes, and auxiliary power networks for rail transit. Through optimized electric field distribution and thermal management structure, the product maintains stable temperature performance during continuous full-load operation, providing long-term reliability for critical power systems. Its design particularly suits scenarios requiring frequent operation and rapid maintenance interventions.
