Product Description
VS1 Indoor Vacuum Circuit Breaker 15kV 630A 50Hz
Product Introduction
The VS1 (ZN63A) series vacuum breaker is an indoor high voltage switchgear designed for 7.2kV, 12kV, 15kV, and 17.5kV three-phase power systems with 50Hz frequency. This breaker provides reliable protection and control of electrical equipment, with exceptional performance for frequent operation at rated current or continuous open circuit conditions.
Featuring an integrated spring operating mechanism and breaker body design, this unit can be installed as either a fixed installation unit or a withdrawable unit with a specialized pushing framework. For applications requiring XGN2 or GG1A cabinets, the fixed type breaker can be equipped with additional interlocks.
Product Reference Standard
Complies with GB1984-89 (Alternating Current High Voltage Breaker), JB3855-1996 (3.6~40.5kV Indoor Alternating Current High Voltage Vacuum Breaker), DL403-1999 (Specification for Order of 10~35kV Indoor High Voltage Vacuum Breaker), and meets relevant requirements of IEC56 (87 publication).
