CDW1-2000 1250/1250 Series Three-Pole Drawer-Type Frame Circuit Breaker (380V Without Undervoltage) Product Introduction
The CDW1-2000 1250/1250 series is a three-pole drawer-type frame circuit breaker specifically designed for 380V AC distribution systems. Developed with modular structural concepts, it meets power protection and control requirements in industrial power distribution, building electrical systems, and energy management applications. With a rated current of 1250A and breaking capacity up to 1250A, this product features compact design and high reliability, delivering essential protection for medium-to-high-end power distribution systems.
The three-pole linkage mechanism adopts drawer-type installation for swift plug-and-play operation, significantly improving maintenance efficiency. A specially designed mechanical interlock effectively prevents misoperation, while the visible contact position indicator allows real-time status monitoring. The built-in voltage adaptation module maintains stable operation during 380V system fluctuations, avoiding unnecessary tripping caused by transient voltage variations.
This series emphasizes intelligent operation support through modular expansion interfaces compatible with multiple signal acquisition units, enabling remote condition monitoring. The contact system combines silver alloy materials with multi-arc extinguishing technology to ensure electrical endurance and breaking reliability under frequent operation scenarios. The optimized mechanical structure achieves both high strength and lightweight characteristics, suitable for various cabinet installation environments.
In terms of environmental protection and energy efficiency, the product aligns with green electrical design principles, exhibiting electromagnetic interference levels notably lower than conventional products. The flame-retardant housing with thermal optimization design reduces operating temperature rise, effectively extending component service life. Ideal for data centers, advanced manufacturing, and rail transit systems requiring high power supply continuity, it provides reliable circuit protection solutions for modern power distribution networks.
