Product Description
The circuit breaker rated insulation voltage up to 800V(NM1-63 type 500V), suitable for AC 50Hz, rated operating voltage up to 690V(NM1-63 type 400V), rated operating current from 10A to 1250A distribution network circuit, Used to distribute power and protect lines and power equipment from overload, short circuit, undervoltage and other faults. At the same time, it can also be used as the motor's infrequent starting and overload, short circuit and undervoltage protection.
Ambient air temperature
The upper limit of ambient air temperature is +40ºC,
The lower limit of ambient air temperature is -5ºC;
The average ambient air temperature for 24h does not exceed +35 ° C.
Elevation: The elevation of the installation site does not exceed 2000m.
Atmospheric conditions: the relative humidity of the atmosphere does not exceed 50% when the ambient air temperature is +40ºC; It can have higher relative humidity at lower temperature; The monthly average maximum relative humidity of the wettest month is 909 and the monthly average minimum temperature of the month is +25 ° C, taking into account the condensation that occurs on the surface of the product due to temperature changes.
Pollution level: The pollution level is 3.
