Application Over Voltage And Under Voltage Protective Device With Auto-Reclosing Function (OUPA) is an intelligent protector integrated with overvoltage protector, under voltage protector and over-current protector. In case of over-voltage fault, under-voltage fault or over-current fault in line, this product can instantly power off to prevent electrical equipment from being burnt. The over-voltage, under-voltage and over-current values of this product can all be set up by yourself and can be adjusted on the basis of local practical condition. II. Product feature 2.1 In case of over-voltage fault, under-voltage fault or over-current fault in single phase line, the product can power off the line and can automatically restore connecting the line over a time delay after voltage of the lien is recovered to normal condition. 2.2 In case of transient over voltage in line, the product can protect the equipment from false operation. 2.3 In case that the line subjects to unstable voltage or sudden power-off and power-on due to loosened connection and other fault, the product will disconnect the line. 2.4 When fault voltage of the line reaches the peak, the product itself will not be damaged. 2.5 Voltage protection range: 0450V for 40A; 0600V for 50A/63A. 2.6 Impulse withstand voltage: 4KV (in compliance with safety standard for electrical appliance of category III). III. Normal use and installation condition 3.1 Normal use condition 3.1.1 Ambient air temperature Ambient air temperature shall not be more than +55° and not le than -20° and the 24h average temperature shall not be more than +35°. 3.1.2 Altitude Altitude of the installation place shall not exceed 2000m. 3.1.3 Atmospheric condition 3.1.3.1 Humidity The relative air humidity at installation place shall not be more than 50% when the ambient air temperature is +40°; Relative humidity may be high under low temperature condition. For instance, when the mean minimum temperature in the wettest month is +20°, the mean maximum relative humidity in the month may reach 90%. Condensation produced due to temperature change shall be prevented by taking appropriate measure. 3.1.3.2 Cla of pollution: 3 3.2 Installation condition 3.2.1 Protector can be vertically or horizontally mounted in cabinet. If specially required, it is neceary to make special order. 3.2.2 Protector shall be mounted in medium without risk of explosion. In the medium, there shall be no gas and conductive dust which are sufficient to corrode metal and affect insulation effect. 4.2.3 Protector shall be mounted in place that may not be invaded by rain and snow.
