This equipment is suitable for a three-phase power system with rated voltage 12kV and frequency 50Hz. It is used to protect and control electrical equipment. Due to special superiority of vacuum circuit breakers, it is especially suitable for frequent operation at rated current or multiple breaking for short-circuit current.
Fixed installation is used mainly for fixed switchgear. This circuit breaker can be used separately. It can be also used for ring network power supply, box-type substation or various non-standard power supply systems.Tel：
