Product Description

LW3 SF₆ Gas Outdoor Circuit Breaker

Product Description

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.
