New type product developed and manufactured by adapting international advanced technology
Supplied with rated insulation voltage 800V and used for circuit of 50Hz AC, rated operating voltage of 400V AC or below rated operation current up to 800A for infrequent changing over and starting of motors
Equipped with protection devices for overcurrent, short-circuit and under-voltage
Capable of preventing damage of circuits and supplying units
Meets IEC 60947-2 standard
Normal working and installing conditions:
Ambient temperature: upper high limit of ambient temperatures is +40C and not higher than +35C averagely within 24 hours. Lower limit of ambient temperature is -5C.
Height above sea level: not more than 2000 meters.
Temperature: Relative humidity should be not more than 50% when the temperature gets to highest +40C. Lower temperature allows higher relative humidity, e.g.: 90% at 25C. Measures should be taken when there's dew due to temperature change.
Pollution class: 2
Installation type: take DIN Rail type TH35-7.5.
