Ndm2 Series Molded Case Circuit Breaker
parameters
Ambient Temperature
◆-35°C-+70°C, the Average Value of 24 Hours Does Not Exceed +35°C. Users Need to Reduce Capacity When It Is Higher than +40°C. for More Information about the Capacity Reduction Coefficient, See "Ndm2 Molded Case Circuit Breaker Temperature Change Capacity Reduction Coefficient Table"
Storage Temperature
◆ -40°C-+75°C
Altitude
◆ the Altitude of the Installation Site ≤ 2500M High Altitude Capacity Reduction Coefficient See "Ndm2 Molded Case Circuit Breaker High Altitude Capacity Reduction Coefficient Table"
Use Relative Humidity/Store Relative Humidity
◆ the Relative Humidity Does Not Exceed 50% When the Ambient Temperature Is +40°C, and the Lower Temperature Can Have Higher Humidity, Such: the Relative Humidity at 20°C Can Reach 90%, and Corresponding Measures Should Be Taken for Frost Caused by Temperature Changes
