CDW3-4000N万能式断路器产品介绍（中英对照）
产品概述：
CDW3-4000N系列万能式断路器采用抽屉水平安装设计，专为AC380V配电系统开发。该产品额定电流达4000A，四极结构设计可有效管理三相四线制配电网络，集成欠电压保护功能，当系统电压低于AC380V时自动触发保护机制。模块化架构配合紧凑型尺寸（具体尺寸需根据技术图纸确认），在保障配电安全的同时优化了设备空间利用率。
核心优势：
-
智能配电管理
通过机械联锁与电气联动的双重设计，配备可视化的分合闸状态指示窗口。控制单元采用模块化接口，支持后期功能扩展需求。操作机构经20,000次机械寿命测试验证，触头系统配置多级灭弧室。
-
多重防护体系
除标准过载和短路保护外，内置电压监测模块可实时检测系统电压波动。当电压持续低于AC380V阈值超过设定延时（0.1-3秒可调），执行机构将自动切断电路，避免用电设备处于非正常工作状态。
-
便捷维护设计
抽屉式结构实现本体与底座快速分离，配备导轨定位装置和三点式机械联锁。维护时通过专用摇柄即可完成本体抽出操作，显著缩短停电维护时间。所有接线端子采用防触碰设计，接触面镀银处理确保导电稳定性。
应用场景：
适用于工业厂房配电柜、商业建筑主配电室、数据中心UPS系统等需要大电流控制的场合。可作配电网络主干线保护开关，或作为电动机组的电源隔离装置。水平安装方式适合标准开关柜的横向布局要求，防护等级满足IP20常规环境使用需求。
CDW3-4000N Moulded Case Circuit Breaker Product Introduction
Product Overview:
The CDW3-4000N series universal circuit breaker features horizontal draw-out installation, specifically engineered for 380V AC distribution systems. With a rated current capacity of 4000A and four-pole configuration, it effectively manages three-phase four-wire power networks. Integrated undervoltage protection activates automatically when system voltage drops below 380V AC. The modular architecture combined with compact dimensions (subject to technical drawings) optimizes spatial efficiency while ensuring power distribution safety.
Key Advantages:
-
Intelligent Power Management
Dual mechanical-electrical interlocking system with visible switching status window. Modular control unit interfaces allow functional expansions. Operating mechanism verified through 20,000 mechanical endurance cycles, equipped with multi-stage arc chutes.
-
Comprehensive Protection
Beyond standard overload and short-circuit protection, built-in voltage monitoring module tracks system fluctuations. Automatic circuit interruption activates when voltage remains below 380V AC threshold for programmable delays (0.1-3s), preventing equipment operation under abnormal conditions.
-
Maintenance Optimization
Draw-out design enables rapid disconnection between unit and base, featuring guide rail positioning and triple mechanical interlocks. Dedicated crank handle facilitates unit extraction, minimizing maintenance downtime. All terminals adopt touch-proof design with silver-plated contacts ensuring conductivity stability.
Application Scenarios:
Suited for industrial plant switchboards, commercial building main distribution rooms, and data center UPS systems requiring high-current control. Functions as main circuit protection or motor group isolation device. Horizontal installation adapts to standard cabinet layouts, with IP20 protection rating for general environments.
