product description
OYV-12 V-630A circuit breaker switch has the advantages of easy installation, less maintenance, long life, small size, low price, safety and reliability. This product meets the technical requirements of GB1984-89 and GB/T1984-2003 AC high-voltage circuit breakers. The main circuit is 630A-20kA (4S), 25kA (3S), and the mechanical life is 10,000 times. The ground loop is 20kA (2S), and the mechanical life is 2000 times.
Precautions for use environmental conditions
The altitude does not exceed 1000m,
The degree of shock does not exceed 8 degrees;
The ambient temperature of the product is -40℃~+140℃,
The daily average relative humidity is not more than 90%, and the monthly average is not more than 90%;
Installation sites with frequent violent vibrations, water vapor, gas, chemically corrosive deposits, salt spray, dust and dirt, and fires, which obviously affect the performance of the mechanism, are not suitable for installation sites with explosion hazards.
