VS1 Side Mounted Vacuum Circuit Breaker
The biggest advantage of VS1 side-mounted vacuum circuit breaker is miniaturization, it can be installed in a small switch cabinet, and its minimum volume can reach 200MM, that is to say, it can be installed in a switch cabinet larger than 200MM.
Model Description
Z:Vacuum circuit breaker
N:Indoor
63:Design Number
12:Rated voltage:12kV
▢: M:Permanent magnet mechanism/blank(mannual type)
▢: Rated current:630A、1250A、1600A
▢: Rated short-circuit breaking current:20kA、25kA、31.5kA、40kA
Working Environment：
1. The ambient air temperature does not exceed + 40°C, the daily average temperature does not exceed +35°C, and the lowest ambient temperature. Air temperature is -15°C. The effect of solar radiation can be ignored.
2. The altitude should not exceed 1000m.
3. Vibration or ground movement from outside the switchgear and control equipment and the normal operation of the equipment formula has no apparent relationship.
4. The surrounding air is not significantly affected by dust, smoke, corrosive and/or flammable gases, vapors air or salt spray pollution.
