VCN3-12 Handcart Vacuum Contactor | High Voltage Power Control

This series of vacuum contactors is a new type of high-voltage indoor switching equipment independently developed by our company based on the current development of the power industry. This product can be used for frequent starting of motors or transformers, and frequency switching of capacitors. The vacuum contactor has a center cabinet handcart structure, which is consistent with the dimensions of ABB's VD4 or VS1 circuit breaker handcart equipped with an 800mm wide center cabinet. It is therefore not necessary to make any modifications to the switchgear in order to assemble and use this product. VCN3 series vacuum contactors are suitable for three-phase AC power systems with rated voltage 12KV and rated power 50HZ. It has a long service life, more than 20 times that of a circuit breaker, has the advantages of frequent operation, stable operation, reasonable functions, low cost, low noise, and small size. The products are used in thermal power plants, metallurgy, petrochemical and other industrial and mining enterprises as switching equipment to control and protect high-voltage motors, transformers, induction furnaces and other loads.
