Medium voltage vacuum contactor

Vacuum contactor uses vacuum arc extinguishing chamber to frequently connect and cut off the normal working current. It is usually used to connect and disconnect 6kV, 380V(660V, 1140V) AC motors with frequent start and stop of medium and low voltage in a long distance.

Product Details

Medium voltage vacuum contactor is a kind of electrical switchgear used in medium voltage power distribution system, which has the characteristics of high reliability and suitable for frequent operation.
Working principle: The core component of the medium voltage vacuum contactor is the vacuum arc extinguishing chamber. When the contactor is closed, the current flows through the contact; when the contactor is opened, the contact gap increases and the current is disconnected in the vacuum. The contact is operated in vacuum, which effectively suppresses arc generation.
Key features:
High operating life: Due to the use of vacuum arc extinguishing technology, the medium voltage vacuum contactor has a very high electrical and mechanical life, suitable for frequent operation.
Compact structure: Compared with the contactor of the same capacity, it is small in size, light in weight, easy to install and integrate.
Low power consumption: Due to the use of permanent magnet drive technology, the auxiliary power consumption of the contactor is low.
High reliability: Vacuum technology eliminates arcs and improves the reliability and safety of the equipment.
Application areas: Medium voltage vacuum contactors are widely used in industry, power plants, mining, ports and other industries, especially suitable for controlling motors, transformers, capacitor banks, etc. When used in conjunction with a fuse, it can be used in systems with short-circuit currents up to 50kA.
