中文版：
CDW3-3200N系列智能型万能式断路器是一款专为现代化配电系统设计的电力保护设备，采用模块化设计理念与智能化控制系统相结合，适用于交流50Hz、额定工作电压AC380V的配电网络。产品采用三极三线制设计，额定电流覆盖2500A应用范围，配备抽屉式安装结构，可实现快速分离与便捷维护，有效提升设备管理效率。
该断路器采用先进的电磁脱扣与电子保护双重机制，集成过载长延时保护、短路短延时保护及瞬时保护功能，实现全时段电流监测与精准动作控制。针对电压波动工况特别配置欠压保护模块，当线路电压低于AC230V时自动执行分断操作，避免设备在异常电压下运行。抽屉式结构配合水平导轨安装设计，既能节省配电柜空间占用，又便于运维人员进行带电状态下的单元抽换操作。
产品核心优势体现在三个方面：其一，优化的触头系统采用特殊合金材料与分弧结构设计，确保高分断能力与长电气寿命；其二，内置智能控制器支持电流参数数字化设定，通过人机交互界面实现保护特性的灵活配置；其三，模块化功能单元支持热插拔更换，显著降低系统维护成本。适用于工业厂房、商业综合体、轨道交通等中低压配电系统的关键节点保护，为电力网络提供多层级安全防护。
English Version:
The CDW3-3200N Series Intelligent Universal Circuit Breaker is a cutting-edge power protection solution engineered for modern electrical distribution systems. Designed for three-phase AC 380V/50Hz networks, this 2500A-rated device combines modular architecture with intelligent control technology. The draw-out type construction with horizontal rail mounting enables swift disconnection and maintenance operations, significantly improving system serviceability.
Featuring dual protection mechanisms with electromagnetic release and electronic trip units, the breaker integrates comprehensive protection functions including overload long-time delay, short-circuit short-time delay and instantaneous tripping. The built-in undervoltage protection module automatically disconnects the circuit when line voltage drops below AC230V, preventing equipment operation under abnormal conditions. The compact draw-out design optimizes panel space utilization while allowing safe live maintenance through modular component replacement.
Key technical highlights include: 1) Advanced contact system with arc-control chamber and special alloy materials ensuring high breaking capacity and extended service life; 2) Digital microprocessor-based protection relay enabling precise current setting adjustment via user-friendly interface; 3) Hot-swappable functional modules minimizing system downtime during maintenance. Particularly suitable for critical power distribution nodes in industrial plants, commercial complexes and rail transit systems, it delivers multi-level protection for medium-low voltage networks.
