Operation Conditions
● When the ambient air temperature is -5°C to +40°C, the mean value is no greater than +35°C within 24 hours.
● Altitude: not higher than 2000m for the installation site.
● When the ambient air temperature is +40°C, the relative humidity of the air shall not be higher than 50%; a higher relative humidity is allowed at a lower temperature; for example, for the wettest month, the maximum relative humidity averaged shall be 90% while the lowest temperature averaged in that month +20°C, and special measures shall be taken for the condensation occasionally produced due to temperature change.
● Pollution grade: Class 3.
● The installation category of the breaker's main circuit is IV and the control circuit and auxiliary circuit being III.
● The circuit breaker should be installed according to the manual.The vertical tilt angle should not exceed 5°.
● If the air circuit breaker is installed in a small compartment of the switch board, the protection grade is up to IP40.
