Indoor Vacuum Circuit Breaker
Description:
VS1-12 indoor permanent magnet high voltage vacuum circuit breaker is indoor switchgear for three-phase AC power system with rated voltage of 50Hz and 12kV. It is used as the protection and control unit for power grid equipment and power equipment of industrial and mining enterprises. Suitable for frequent operation or multiple breaks short circuit currents at rated operating current.
The circuit breaker adopts the integrated design of the operating mechanism and circuit breaker body, which can be used as a fixed installation unit or equipped with a special propulsion mechanism to form a handcar unit.
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.
