Vacuum contactor is an electrically controlled switch that is used to make or break an electrical circuit with the help of vacuum interrupter, relay and fuse. It is mainly found in motor starters, switchgear and control gear of medium voltage fast switching devices. The vacuum contactors are used for those applications that require low to moderate continuous load current, very frequent switching operations, and very high endurance.
The Global Vacuum Contactor Market will grow from an estimated value of USD 3.43 Billion in 2015 to USD 4.81 Billion by 2020 with a CAGR of 7.04% from 2015 to 2020.Growth in the related as well as complementary markets, such as motors, capacitors, switchgear, and transformer, also contribute towards the growth of vacuum contactors.
Vacuum contactors are mostly used in power plants, transmission, and distribution substations of power utility companies. They are used for blowers, water pumping, conveyors, capacitor switching, and other power switching applications. With the growing transmission and distribution network across globe, the number of substations will keep on increasing. This increasing number of substations would further increase the use and demand of vacuum contactors.
