Circuit Breaker>>Intelligent Circuit Breaker>>AW45 Series
AW45 series intelligent circuit breaker (hereinafter referred to as breaker) is suitable for thecircuit of AC 50Hz with rated voltage 400V, 690V and rated current up to 6300A .It is mainly usedto distribute electric energy and protect circuit and power supply equipment from overload, un-der-voltage short-circuit ,and single-phase earthing .With intelligent and selective protectionfunctions, the breaker can improve the reliability of power supply, and avoid unnecessary powerfailure . The breaker is applicable for power stations, factories , mines(for 690V) and modernhigh-building, especially for the distribution system of intelligent building. The breaker conforms to IEC60947-2. The whole series have past CCC certification and CEcertification.
2. Environment conditions for operation
Temperature condition: -5oC~+40oC; the average value within 24h not exceed +35oC. Elevation: altitude of installation place shall not exceed 2000m. Atmosphere condition: relative humidity at +40oCshall not exceed 50%. Higher humidity ispermissible at lower temperature condition. When the higher monthly average relative humidityis 90% in the humiddest month , the lowest monthly average temperature of this month is +25oC.And consider the influence of dew on product surface due to temperature changes. Pollution grade: gradeIII. The breaker should be installed according to the requirement on the instruction manual: thevertical inclination degree shall not exceed 5oC
