This series vacuum contactor is made of high quality vacuum switch, with a metal frame and insulated bracket has the performance of well breaking
Apply to 7.2 kv, 12 kv single phase or two in the electric power network system, for long distance through and points to break, frequent start and control resistance sex perceptual and capacitive load and so on. Unipolar series are often used to back away in the loop arc, harmony, pick up the landlord switch as , with small size, the whole, break-brake speed, strong ability to break points, etc.
