Operation Conditions for Air Circuit Breakers

Air switches are not suitable for every location; they have specific requirements for the working environment, such as air humidity, temperature, altitude pressure, and contamination levels.

Ambient Air Temperature: Maximum +40℃; Minimum -5℃; the average ambient air temperature over 24 hours should not exceed +35℃.

Altitude: The installation site's altitude does not exceed 2,000m.

Atmospheric Conditions: Relative humidity should not exceed 50% when the surrounding air temperature is +40℃; higher relative humidity is permissible at lower temperatures; the monthly average relative humidity for wet months is 90%, with a monthly average low temperature of +25℃, taking into account condensation on the product surface due to temperature changes.

Contamination Level: The contamination level is rated at 3.
