1. Overview
. High-voltage vacuum single-phase contactor is suitable for indoor power systems with voltages of and below and working current of 3 and below. It has strong breaking capacity, long life and easy maintenance. Small quantity, no arc exposure, safe and reliable, small size, light weight, low noise, and can be used reliably in harsh environments and frequent operations. Suitable for coal, petroleum, chemical industry, metallurgy, electric power, machinery, transportation and other fields. It can be used for arc suppression devices, grounding protection or switching other electrical loads.
2. Environmental conditions
. The upper limit of ambient air temperature + ℃ and the lower limit - ℃ b. The altitude does not exceed.
The daily average relative humidity is not greater than, the monthly average is not greater than the water vapor pressure, the daily average is not greater than. The monthly average is not greater than.
.The surrounding air should not be significantly contaminated by corrosive or flammable gases, water vapor, etc.
.No frequent violent vibrations.
When the contactor is running, the inclination angle between the installation plane and the horizontal plane should not be greater than .
