  •  1.Operating environment

    a.Do not install in an environment containing explosive gas,or there is a risk of explosion.
    b.Do not install it in a place where rain or snow strikes.
    C.Do not install it in a place where the vibration acceleration is greater than 0.7g.
    d.Do not install in places where gas medium can corrode metal and destroy insulaton.

     

    2.Circuit breaker installation place environmental requirements

     Ambient air temperature:-5℃~+40°℃,and 24h average value does not exceed+35℃.

     Relative humidity:The average minimum humidity of the wettest month Relative shall not exceed+25℃,and the average maximum relative temperature of the month shall not exceed humidity 90%,taking into account the condensation occuring on the surface of the product due to temperature changes
