Chint Over-voltage Under-voltage Protection Relay 230V/400V Home or Industrial Use in 1-phase or 3-phase

OUVR-1 self-recovery over-voltage protector is a new type of intelligent protection device. The product adopts modularization standard design.
Overvoltage occurs in the power supply line. When the voltage is under voltage, the protector can cut off the circuit quickly and safely under continuous high voltage impact.

An abnormal voltage is sent to the terminal electrical appliance to cause an accident. When the voltage returns to the normal value, the protector will automatically connect within the specified time.

Through the circuit, ensure that the terminal appliances operate normally under unattended conditions.

OUVR-1 self-recovering overvoltage and undervoltage protector for AC voltage 230/400V, frequency 50Hz, rated working current
Users or loads of 80A and below. Mainly used in residential distribution boxes or other distribution lines that need protection.

Features
1.1 Prevent malfunction: When the line has sudden transient or transient over-voltage, the protector does not cause malfunction;
If the voltage is unstable or suddenly powers off and suddenly calls, the protector does not connect to the line;
1.2 Reliable action: protection is anti-time action characteristics, action time ≤ 1s;
1.3 Wide voltage protection range: 0~450V; when the line fault voltage is the highest, the protector itself will not be damaged;
1.4 Safer, withstand surge voltage: 4kV (in accordance with the safety standards of Class III electrical appliances);
1.5 Status indication: The protector has LEDs to indicate the working status, green is the normal voltage indication, red overvoltage refers to
Indication or undervoltage indication;
1.6 Shape modular design, rail mounted.
