Overview:
vacuum circuit breaker, with different high voltage, three-phase AC-50HZ  switchgear components, which is used with  switch cabinet and also install in fixed switch cabinet and so on. The breaker is designed with spring operating organization and breaker itself, which can be used in fixed installation unit, also matched with specialized pushing mechanism and make up handcart type as usage.All products conform to GB1984-2003,JB/T3855-2008,DL/T403-2000 and IEC62271-100:2001 standard rule.

The advantage :
 vacuum circuit breaker maintains the feature small volume, high breaking intensity, high insulating intensity, no pollution, no exploding risk, and also have such advantage as follow:
1. Solid-sealed polar pole structure: It is made of high-intensity Epoxy resin materials and designed by APG craft, solid-seal the vacuum interrupter and Top/bottom line together, avoid of possible destroy from outside and no-maintenance.
2. Special appearance design: Our products are strictly designed according to international standard, have superior design idea by professional research organization in China.
3. High corrosion resistance: All components are made of high quality Nickel- Phosphorus metal materials, which is to improve the capacity of high pollution resistance , corrosion resistance and enhance the lifetime.
4. Long lifetime: the mechanical lifetime of our vacuum circuit breakers has elevated to 30000 times from 20000 times when the breaking current is below 31.5KA; and elevated to 20000 times from 10000 times when the breaking current is 40KA.
5. High reliable secondary system: All components are made of super raw materials, enhance the stability and reliability.
6.High insulating intensity: It is used under elevation 2000m environment, which can meet the insulating need with no need to change any parts.

The usage environment:
1. The temperature in surrounding air: Max:+40°C~Min -15°C,The average:<=+35°C
2. Humidity: The average of relative temperature within 24hours is <=95%, The average of Water vapour pressure within 24hours is <=2.2kpa.
3. Here is no serious pollution from dust, smoke, corrosive or combustible gas, vapor or salt spray, and so on.
