China Vcb Vd4 12kv 630A Indoor High-Voltage Vacuum Circuit Breaker
Project Description:
VS1indoor vacuum circuit breaker is an indoor switchgear for a 24KV rated voltage 50Hz power system. It is the protection and control unit for power equipment in power grids and industrial and mining enterprises. Suitable for frequent operations or locations with multiple short-circuit currents under rated operating current. The circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body. It can be used as a fixed installation unit or equipped with a dedicated propulsion mechanism to form a handcart unit.
Suitable for various places:
1. Control and protection of industrial electrical equipment.
2. Mining enterprises.
3. Power plants.
4. Substation.
It can be fixed in the switchgear or installed on a handcart.
Stable performance and easy installation.
Advantage
1. Simple structure.
2. Adopting ultra-low resistance vacuum arc extinguishing chamber.
3. Adapt to optimized and modular spring operating mechanisms.
4. Suitable for situations with frequent operations.
5. No maintenance, long service life.
6. Reliable performance.
