塑殼斷路器CDM1-250L/4340 250A AC230V
產品概述
CDM1-250L/4340塑殼斷路器是一款高性能配電保護設備，額定電流250A，工作電壓AC230V，適用于交流50Hz-60Hz的配電網絡。該產品采用熱磁式脫扣技術，能有效實現過載、短路和欠電壓保護，確保線路及負載設備的安全運行。其設計緊湊，分斷能力高，飛弧距離短，同時具備抗震動特性，適用于工業、商業及基礎設施等多樣化場景。
核心功能
斷路器通過熱磁脫扣器實現精準保護：雙金屬片熱脫扣響應過載電流，電磁脫扣瞬時動作于短路電流。模塊化結構支持手動操作，并可擴展電動操作附件（如電操機構AC220V/380V）。產品極數為4P（4340表示4極3段保護），殼體采用高強度絕緣材料，符合工業環境耐用需求。
技術特點
CDM1-250L/4340具備20000次機械壽命，額定絕緣電壓690V，支持垂直或水平安裝。其分斷能力分級明確（L型為標準分斷級別），適用于電動機保護或動力配電系統。產品提供多種額定電流選項（100A-250A），用戶可根據實際需求靈活選配。
應用場景
廣泛應用于建筑配電、機械制造、能源設施等領域的電能分配與設備保護，尤其適合需要高可靠性和穩定性的場合。
Product Overview
The CDM1-250L/4340 moulded case circuit breaker is a high-performance protection device with a rated current of 250A and operational voltage of AC230V, designed for 50Hz-60Hz AC power distribution systems. It integrates thermal-magnetic trip technology to deliver reliable overload, short-circuit, and undervoltage protection, ensuring the safety of electrical circuits and connected equipment.
Key Features
Equipped with a 4-pole configuration (4340 indicates 4 poles with 3 protection stages), the breaker features a compact design, high breaking capacity, and short arcing distance. The robust insulated housing enhances durability in harsh environments, while manual operation can be upgraded with motorized mechanisms (e.g., AC220V/380V).
Technical Specifications
With a mechanical lifespan of 20,000 cycles and an insulation voltage of 690V, the CDM1-250L/4340 supports both vertical and horizontal mounting. Its standardized breaking capacity (L-type) makes it suitable for motor circuits and power distribution panels. Multiple current ratings (100A-250A) are available for customized solutions.
Applications
Ideal for industrial plants, commercial buildings, and infrastructure projects requiring stable power distribution and equipment protection.
