VSC1(VBM7)-12 Indoor High Voltage Vacuum Circuit BreakerDetailed product description：

VSC1 (VBM7) -12 indoor high-voltage vacuum circuit breaker is an indoor high-voltage switchgear suitable for use in three-phase power systems with a rated voltage of 12 kV and a frequency of 50HZ. It is used as a protective and control electrical device. Due to the special advantages of vacuum circuit breakers, it is particularly suitable for frequent operation at rated current or multiple short-circuit current breaking locations. The VSC1 (VBM7) -12 indoor high-voltage vacuum circuit breaker adopts a fixed installation and is mainly used for fixed switchgear. This circuit breaker can be used independently or for ring network power supply, box type transformers, or various non-standard power supply systems.
