DW17-1900 630/630 4P Molded Case Circuit Breaker Product Introduction (English Version)
The DW17-1900 series molded case circuit breaker is an intelligent power protection device developed for modern distribution systems. Featuring a 4-pole (4P) structural design, it is suitable for AC power networks with rated voltage of 220V and rated current of 630A. Equipped with electric quick-operating mechanism, the product enables flexible switching between remote control and local operation, meeting the efficient management requirements of industrial automation scenarios.
The product adopts modular construction, with its main frame precision-cast from high-strength alloy materials. The critical contact components utilize composite silver-based contact technology, effectively reducing contact resistance and enhancing conductive stability. The arc-extinguishing system incorporates multi-stage arc-guiding partitions and gas dynamic ventilation channels, capable of interrupting fault current within 8-15 milliseconds while significantly reducing arcing duration. The operating mechanism has passed 200,000-cycle mechanical endurance tests, demonstrating reliable repetitive operation accuracy for frequent switching scenarios.
An intelligent status indication interface features dual-color LED groups to display real-time switching status, energy storage state, and fault warnings. The ergonomic mechanical interlock prevents misoperation risks, with vertical installation compatibility for standard cabinet rail systems. The product is particularly suitable for data centers and smart manufacturing lines requiring high power supply continuity, capable of building multi-level selective protection networks while adapting to renewable energy grid-connected systems.
Environmental considerations include strict compliance with hazardous substance control requirements. The flame-retardant corrosion-resistant composite housing ensures stable operation within -25℃ to +70℃ temperature range. Optimized cooling fin design coupled with convective airflow channels maintains long-term operational temperature rise at 60% below industry standard limits, significantly extending service life.
