I. 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 features
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: 0-450V for 40A; 0-600V 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 conditions
