13.5 Derating at highertemperatureBy derating the current to 80% of nominal current, the<strong>MSF</strong> can be operated at an ambient temperature of up to50 °C. E.g. a <strong>MSF</strong>-045 can operate a heavy load of 36 A (45A*0.8).13.6 Environmental conditionsNormal operationTemperature 0 - 40°CRelative humidity95%, non-condensingMax altitude without derating 1000 mStorageTemperatureRelative humidity-25 - +70°C95%, non-condensing13.7 StandardsMarket Standard DescriptionAllEuropeanIEC 60947-1IEC 60947-4-2EMC DirectiveLow Voltage DirectiveLow voltage switch gear and control gear - Part 1: General rules.Low voltage switch gear and control gear - Part 4-2: Contactors and motor starters -AC semiconductor motor controllers and starters2004/108/EC2006/95/ECRussian GOST R Russian certificate of conformityAmericanUL 508CSA 22.2 No. 14-05Industrial control equipment.UL: Models <strong>MSF</strong>-017 to <strong>MSF</strong>-835 up to 600 VACcUL: Models <strong>MSF</strong>-017 to <strong>MSF</strong>-250 up to 600 VACRadiated and conducted emission: Class A (industrial environment).For class B (public environment) an externalbypass has to be used.120 Technical data <strong>Emotron</strong> AB 01-4135-01r2
