Product Description
Product description
MV vacuum contactor has the features of energy saving, f ire protection, explosion-proof, small size, long life, low maintenance cost, reliable operation and non-polluting and so on ,which is w idely used in metallurgy, mining, petroleum, chemical, railway, radio, communications, industrial high-frequency heating industry, energy, transportation and other power distribution system. With the technology of break ing the current , high reliability and compact structure, the contactor can be used in particularly harsh conditions. They are suitable for the control and protection (with fuses) lines, substations and distribution stations, motors, transformers, capacitors and so on.
