CDM6S-800M/3348 500A 固定式板后接線塑殼配電保護裝置產品介紹
中文版：
CDM6S-800M/3348 500A固定式塑殼配電保護裝置是專為工業配電系統設計的核心保護設備，采用優化的結構布局與模塊化設計理念，適用于額定電流500A的配電場景。產品主體結構選用高強度復合工程材料，配合精密壓鑄工藝，在保持緊湊體積（外形尺寸為XXXXXXXXX mm）的同時，顯著提升機械強度與絕緣性能。
該裝置采用板后接線設計，有效節省配電柜前端操作空間，便于在有限空間內實現多回路并行布局。三極四線結構（3348配置）可同步監測三相電流與中性線狀態，集成過載長延時、短路瞬時三段式保護特性，動作時間精度控制在±5%以內。創新設計的雙斷點觸頭系統配合電弧快速分斷技術，使分斷能力達到XXkA等級，確保在故障電流出現時能快速切斷電路。
人性化設計體現在可視化分合閘指示窗與操作手柄聯動機構，支持正面直接觀察運行狀態。模塊化附件槽設計便于后期擴展報警觸點、分勵脫扣等輔助功能模塊。防護等級達到IP65（安裝后），適用于粉塵、潮濕等復雜工業環境。接觸部件采用銀鎳合金復合材料，經20000次機械壽命測試后仍保持穩定的接觸電阻值。
典型應用包括制造車間主配電柜、商業綜合體動力配電間、軌道交通輔助供電系統等需要大電流保護的場合。安裝時建議預留不小于XXmm的散熱空間，并配合專用安裝導軌實現快速定位。維護周期建議按使用環境差異設定為3-5年，可通過觀察窗檢查內部滅弧室狀態。

CDM6S-800M/3348 500A Fixed Rear-Terminal Molded Case Circuit Protection Device
The CDM6S-800M/3348 500A fixed-type molded case protection device is engineered for industrial power distribution systems, featuring optimized structural configuration and modular design. Suitable for 500A rated current applications, its main body utilizes high-strength composite engineering materials combined with precision die-casting technology, achieving compact dimensions (XXXXXXXXX mm) while enhancing mechanical durability and insulation performance.
The rear-terminal connection design maximizes front-panel accessibility in distribution cabinets, enabling efficient multi-circuit arrangements within confined spaces. The 3P4L (3348 configuration) structure provides simultaneous monitoring of three-phase currents and neutral line status, integrating three-stage protection characteristics including overload long-time delay and short-circuit instantaneous tripping, with operational time accuracy maintained within ±5%. The innovative double-break contact system coupled with arc-quenching technology delivers breaking capacity up to XXkA level, ensuring rapid circuit interruption during fault conditions.
User-centric design elements include a synchronized position indicator window and operating handle mechanism, allowing direct visual confirmation of device status. Modular accessory slots facilitate post-installation expansion with auxiliary functions such as alarm contacts or shunt trip modules. With post-installation IP65 protection rating, the unit withstands challenging environments containing dust or moisture. Silver-nickel alloy composite contacts maintain stable resistance values after 20,000 mechanical operation cycles.
Ideal applications encompass manufacturing plant main distribution boards, commercial complex power rooms, and rail transit auxiliary supply systems requiring high-current protection. Installation requires minimum XXmm heat dissipation clearance and utilizes dedicated mounting rails for precise positioning. Recommended maintenance intervals range 3-5 years depending on operational environment, with internal arc chamber condition verifiable through inspection windows.
