VS1 (ZN63A) indoor high voltage vacuum circuit breaker

An overview of the indoor high-voltage vacuum circuit breaker
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 special propulsion mechanism to form a handcart unit. The fixed circuit breaker can add corresponding connections. Locks to meet the needs of fixed cabinets.
Three products based on standards
The circuit breaker complies with the standard requirements of "AC High Voltage Circuit Breaker", "Internal AC High Voltage Vacuum Circuit Breaker"/"Technical Conditions for Ordering Pressure Vacuum Circuit Breaker" and meets the relevant requirements of the publication.
