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
结构特点
该断路器采用框架式结构，主要部件包括操作机构、触头系统、灭弧室和智能脱扣器等。操作机构位于设备右侧，通过主轴与触头系统联动，面板配备分合闸状态指示及手动操作按钮。灭弧系统采用多栅片设计，能快速熄灭电弧。产品采用板前垂直接线方式，母排连接处使用特殊处理工艺确保导电性能。无欠压脱扣器配置简化了安装要求，使产品更适用于电压波动较大的工业环境。抽屉式设计版本还可实现快速更换维护，提高系统可用性。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
