Product Description
The VS1-12 indoor high-voltage vacuum circuit breaker (also known as ZN63A-12) is designed for use as a complete indoor switchgear in 50 Hz AC power networks with a voltage of 3-10 kV. The switch performs protection and control functions for network equipment, as well as for power plants of industrial enterprises and mining operations.
Thanks to its excellent characteristics, this vacuum circuit-breaker is particularly well suited for applications requiring frequent switching at the rated operating current, as well as for repeated breaking of short-circuit currents.
The VS1-12 switch is available in two versions according to the type of drive: with a spring mechanism and with a magnetic mechanism. It can be supplied either in a stationary version or complete with a special withdrawable mechanism for assembly in a withdrawable version.
