MEDIUM VOLTAGE VACUUM CONTACTORS MARKET ANALYSIS

Market Challenges And Opportunities

Vacuum contactors are 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. For example, in the case of 60HZ power (U.S. standard), the power will discontinue within 1/120 or 0.008333 of a second. Medium voltage vacuum contactors are load breaking devices with a limited short-circuit making and breaking capacity for applications with high switching rates of up to 1 million operating cycles. Advantages associated with using a vacuum as a switching medium are long electrical and mechanical life, extremely compact size and no arc chutes or blow out coils. Thus, the market of medium voltage vacuum contactor is expected to grow with growth of the Heating, Ventilation and Air Conditioners (HVAC) application.
