Over Voltage And Under Voltage Protective Device With Auto-Re closing Function (OUPA) is an intelligent protector integrated with over voltage 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
3.1 Normal use conditions
3.1.1 Ambient air temperature
Ambient air temperature shall not be more than +55℃ and not less than -20℃ and the 24h average temperature shall not be more than +35℃.
Altitude of the installation place shall not exceed 2000m.
3.1.3 Atmospheric conditions
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.

V. Product setting:
5.1： Press and hold on the “set” key for 3s, entering into setting status;
5.2： When over voltage indicator lamp lights up, set up the over voltage value by pressing the “up” key or “down” key to increase or decrease the over voltage value which can be 230V-300V (default: 270V).
5.3: Press the “set” key, when under-voltage indicator lamp lights up, set up the under-voltage value by pressing the “up” key or “down” key to increase or decrease the under-voltage value which can be 145V-210V, (default: 170V).
5.4: Press the “set” key, when current indicator lamp lights up, set up the over-current value by pressing the “up” key or “down” key to increase or decrease the over-current value which can be 1A-63A (adjustable) (default: 40A).
5.5: After the setting, stay for 40s before powering on.
5.6： Press the “up” key and “down” key together to restore factory setting.
After being installed, the protector can be wired by user. Wherein, cross section of the wire shall be selected in accordance with standard applicable and on the basis of rated current of the protector. Pay attention to the locations of incoming and outgoing wires and the phase sequence before powering on for use.
8.1 The input and output shall be corrected connected on the basis of the product marking. (Wherein, the load current shall be less than protective current of the product. )
8.2 Neutral line N cannot be improperly connected and shall be reliably wired; otherwise, the protector may not work normally.
8.3 Before powering on, please carefully check whether the wiring is correct, whether the load matches with protective current of the product and whether the binding screw is tightened; otherwise, the product may be damaged.
8.4 After powering on the product, don’t touch any live part to avoid electric shock.
8.5 This product shall be combined with micro circuit breaker to play a role of short-circuit protection; otherwise, the product may not be able to realize load limit protection in case that input or load end of the product appears short circuit.
8.6 As the product has automatic reset function, after the product plays the role of protection and acts, it is necessary to remove the load (electric appliance) and check the circuit; otherwise the product will be frequently connected and disconnected to the load. Finally, the product or its circuit may be burnt due to frequent overload connection and disconnection for long time.
