Product Description
Product Description
Vacuum contactors utilize vacuum bottle encapsulated contacts to suppress the arc. This arc suppression allows the contacts to be much smaller and use less space than air break contacts at higher currents. As the contacts are encapsulated, vacuum contactors are used fairly extensively in dirty applications, such as mining.
Vacuum contactors are only applicable for use in AC systems. The AC arc generated upon opening of the contacts will self-extinguish at the zero-crossing of the current waveform, with the vacuum preventing a re-strike of the arc across the open contacts. Vacuum contactors are therefore very efficient at disrupting the energy of an electric arc and are used when relatively fast switching is required, as the maximum break time is determined by the periodicity of the AC waveform.
Henan Huaruitongbao Electric is a high-tech enterprise, specialized in manufacturing high voltage vacuum contactors, outdoor & indoor high voltage vacuum circuit breakers, high voltage vacuum load switch, HV whole-sets electric equipments, automatic reactive compensation devices, and other products, widely used in coal, electricity, mining, cement, and chemical industry.
