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.

PERFORMANCE FEATURE

 Performance Advantages
 1. SF6 gas is a non-toxic, non-flammable electrical insulating gas with excellent arc extinguishing characteristics.
 2. In addition to the standard ceramic casing, a variety of options are available, including rubber insulators on epoxy equipment casing.
 3. The color-coded main contact position indicator (green - open; red - closed) is easily visible from the floor and is directly connected to the main contact drive shaft assembly to ensure accurate indication of contact status.This indicator is directly connected to the main contact drive shaft assembly to ensure accurate indication of contact status.

 4. A spring-loaded operating mechanism ensures fast closing and opening operations (less than 110ms).
 5. Backup electronic controller for local operation and FTU/RTU interface for main console operation

 6. The switch is made of proven rugged, corrosion-resistant material (304L stainless steel plate for warships), ensuring a long service life (30 years) and the ability to implement a range of
 The switches are made of proven, rugged, corrosion-resistant materials (304L stainless steel plate for naval vessels) to ensure a long service life (30 years) and the ability to perform a wide range of operations with the desirable characteristics of column-mounted equipment.
 7. Each switch has been filled with SF6 gas, sealed and tested according to IEC60265-1 (1988) and GB3804-1990 standards before leaving the factory.
