The ZW32-12/630-20 outdoor vacuum circuit breaker is a three-phase AC power distribution device with the rated voltage of 12kV and the rated frequency of 50Hz.
Mainly used to break and close the load current, overload current, and short-circuit current in power systems, this outdoor vacuum circuit breaker is suitable for control and protection in power distribution systems of substations as well as industrial and mining enterprises. It is also applicable to occasions requiring frequent operations in rural power grid.
Features of the Outdoor Vacuum Circuit Breaker
1. The fully-enclosed structure ensures outstanding sealing performance and moisture-proof, non-condensing properties, which makes this product ideal for use in extremely cold or humid areas.
2. The 3-phase support and current transformer are safe and reliable by the adoption of outdoor epoxy resin insulator or indoor epoxy-coated organic silicone rubber insulator.
3. Strong resistance to aging, UV light, high and low temperatures
4. Small spring actuating mechanism and long-lasting permanent magnet device with superior sealing performance and strong corrosion resistance
5. The circuit breaker can withstand various conditions such as dust, smoke, corrosive gas, steam or salt mist.
6. This product can work normally over temperatures ranging from -40℃ to +45℃. It has been used at -40℃ and at an altitude of 4,000m in places such as Heilongjiang, Xinjiang, Qinghai, etc.
7. Max. rated current: 1250A, Rated breaking current: 25kA
8. Rated short-circuit breaking capacity: 30 times
9. Machine service life: 10000 times and 30000 times (permanent magnet system)
10. IP rating: IP65
