核心功能特性
產品采用電磁式脫扣原理，具備過載長延時和短路瞬時雙重保護功能，電流整定范圍覆蓋(0.64-1.0)In至(5-10)In。六開六閉輔助觸頭配置（6常開+6常閉）支持多路信號傳輸與控制，電氣壽命超過500次分斷操作。電動操作機構支持遠程控制，在85%-110%額定控制電壓范圍內均可可靠閉合，飛弧距離控制在350mm以內確保安裝安全性。獨特的抽屜式結構設計便于維護，水平/垂直進出線方式適應不同柜體布局。46
Technical Specifications
The DW16-4000 3200A electro-magnetic molded case circuit breaker is designed for 50Hz AC power distribution networks with rated operational voltage of 380V. Featuring a 4000A frame size and adjustable current setting from 800A to 3200A, it employs motorized operation mechanism with six NO+NC auxiliary contacts (6-open/6-close configuration) for comprehensive circuit monitoring. The triple protection system integrates thermal overload delay and instantaneous short-circuit tripping functions, with arc chutes effectively limiting arc distance to 350mm. Its modular construction allows both horizontal and vertical busbar connections in switchgear cabinets.112
Application Scenarios
This breaker is widely deployed in power distribution centers of manufacturing plants, commercial buildings and infrastructure projects. Typical applications include main feeder protection for 380V transformer secondary circuits, motor control center backup protection (for 630A+ motors), and bus-tie applications in dual-source systems. The motor-driven mechanism enables integration with SCADA systems for automated power management, while the 6-form auxiliary contacts facilitate interlocking with other protective devices. The product s robust construction ensures reliable performance in environments with ambient temperatures from -5°C to +40°C.317
