Product Overview
Description
A complete set of primary and secondary integrated pole circuit breaker
Description: ◆Type LW3-12/630-20 column mounted circuit breakers are suitable for use with a rated voltage of 12kV
◆Rated current 630A, 50/60Hz distribution network off
◆Turning off the load current and overload current in the power system can automatically separate the fault distribution circuit segments
◆Switches with the latest technology of electronic controller, manual operation, electric operation and remote operation
◆The electronic controller is housed in a stainless steel case and can be used in all weather conditions
◆In addition, the box can also be installed with wired and wireless modems, which can achieve remote monitoring and control
◆Simple column installation and arrangement is convenient and fast, reducing the construction cost.
