Featuring a three-dimensional layout structure with separated contact system and arc extinguishing chamber, it enables rapid circuit breaking and closing through electric quick-action mechanism. The vertical fixed mounting saves space and facilitates maintenance, with current ratings ranging from 630A to 1900A, making it particularly suitable for high-current power distribution systems. Its modular design incorporates intelligent trip units for effective protection against overload and short circuit faults, while supporting remote control and status monitoring functions. 51016
結構特點
該斷路器采用框架式結構，主要部件包括操作機構、觸頭系統、滅弧室和智能脫扣器等。操作機構位于設備右側，通過主軸與觸頭系統聯動，面板配備分合閘狀態指示及手動操作按鈕。滅弧系統采用多柵片設計，能快速熄滅電弧。產品采用板前垂直接線方式，母排連接處使用特殊處理工藝確保導電性能。無欠壓脫扣器配置簡化了安裝要求，使產品更適用于電壓波動較大的工業環境。抽屜式設計版本還可實現快速更換維護，提高系統可用性。71219
Structural Features
The circuit breaker employs a frame-type structure comprising operating mechanism, contact system, arc extinguishing chamber and intelligent release unit. The operating mechanism positioned at the right side connects with contact system through main shaft, featuring status indicators and manual operation buttons on panel. Multi-splitter arc chute ensures rapid arc extinction. Front-mounted vertical wiring terminals with specially treated busbar connections guarantee optimal conductivity. The exclusion of undervoltage release simplifies installation requirements, making it more adaptable to industrial environments with voltage fluctuations. Drawer-type versions allow quick replacement and maintenance to enhance system availability. 21420
應用領域
本產品適用于工業配電系統、商業建筑供電網絡、發電廠及變電站等場合，可實現對主配電線路和重要用電設備的保護。在電動機控制領域，能夠為630A以下電機提供過載和短路保護。其穩定的性能表現使其成為配電系統關鍵節點的理想選擇，尤其適合需要頻繁操作但無需頻繁轉換的電路環境。產品設計考慮了多種工業環境因素，能在-5℃至+40℃溫度范圍和海拔2000米以下地區穩定工作。1615
Application Fields
This product is suitable for industrial power distribution systems, commercial building supply networks, power plants and substations, providing protection for main distribution lines and critical electrical equipment. In motor control applications, it offers overload and short-circuit protection for motors below 630A. Its reliable performance makes it an ideal choice for critical nodes in power distribution systems, particularly suitable for circuits requiring frequent operation but not regular transfer. The design accommodates various industrial environmental factors, ensuring stable operation in temperature ranges from -5℃ to +40℃ and altitudes below 2000 meters. 81318
