5. installation: 3P 400A MCCB

1)The temperature maximum rate around the device should not be over +40°C, the minimum temperature

should not be lower than -5°C, and the average temperature in 24h should not be higher than +35°C.

Note1: when the working condition has the minimum temperature -10°C to, customer should declare to

manufacturer when ordering the device.

Note2: when maximum temperature is over +40°C or minimum is lower than -25°C in working condition,

customer should consult the factory.

2)The altitude of the place where the machine be installed in should not be higher than 2000 meters.

3)The relative humidity of atmosphere should not be above 50% when the surrounding temperature is +40°C.

It is allowed to work in comparatively high relative humidity when the temperature is comparatively low. For instance,

when the relative humidity reaches 90% in +20°C, user should take some appropriate treatments to

get rid of the occasionally appeared moist.

4)Class of pollution: Class 3

5)Category of installation: circuit breaker main circuit is category , control circuit and auxiliary circuit are category
