PRODUCT DETAILS


Indoor Vacuum Circuit Breaker

Description:
        ZN63C-12 (VS1-12C) type indoor side installed high voltage vacuum circuit breaker is indoor high voltage switchgear is suitable for three-phase power system with the rated voltage 12kV, frequency 50Hz, used as a protective and control equipment, due to the special advantages of the vacuum circuit breaker, particularly applicable to frequent operation under the rated current, or multiple breaking short circuit current location ZN63C-12 (VS1-12C) type indoor side installed high voltage vacuum circuit breaker adopts fixed installation, mainly used for fixed type switch cabinet, the circuit breaker can be used separately, but also can be used for ring network power supply, box-type substation or various non-standard power supply system.
