Product Description

Jcz5-7.2kv 250A AC H. V. 3 Phase Mechanical Holding Vacuum Contactor for Substation

General description

JCZ5- 7.2KV series indoor AC high-voltage vacuum contactors are divided into two types: mechanical holding and electromagnetic holding. This contactor is suitable for power systems with three-phase AC 50HZ, rated voltage 7.2KV, and rated current up to 630A. It is used for long-distance connection and disconnection of lines, control of high-voltage motors, transformers and capacitive loads and other electrical equipment. It is especially suitable for various electrical equipment. Fields of frequent operation. The contactor is small in size and light in weight. It adopts the international popular assembly structure of upper and lower arrangement, which is easy to use and maintain, and it is easy to form a complete set of F-C circuit equipment.
Widely used in power grid reactive power compensation, petrochemical, metallurgy, water supply and drainage treatment, coal mine underground equipment and other occasions.
