OUVR-1 Self-recovery Overvoltage and Undervoltage Protector

1. Product Features

1.1 Preventing misoperation: Where sudden transient or temporary overvoltage occurs in the line, the protector will not generate misoperation; when the line suffers instable voltage or sudden power recovery after sudden power disruption due to loose contact or other fault, the protector will not close the circuit;

1.2 Reliable operation: Protection is characterized by inverse time lag operation with operating time

1.3 Wide scope of voltage protection: 0-450V; in case of maximum fault voltage upon line fault, the protector itself will not be damaged;

1.4 Safer, impulse withstand voltage: 4kV (conforming to the safety standard of category Ⅲ electrical apparatus);

1.5 Condition indication: The protector has the LED to indicate the operating state, where green is normal voltage indication, and red is overvoltage or undervoltage indication;

1.6 External modular design, guiderail DIN rail mounting.

2. Scope of Application

OUVR-lself-recovery overvoltage and undervoltage protector is a new type of intelligent protection apparatus. With the modular standard design, in case of the overvoltage or undervoltage of power supply line, the protector can quickly and safely break the circuit under continuous high voltage surge, avoiding the happening of an accident due to abnormal voltage entry into the terminal apparatus; when voltage resumes normal value, the protector will automatically close the circuit within the specified time to ensure the terminal apparatus can operate normally in an unattended way.

OUVR-lself-recovery overvoltage and undervoltage protector is applied for the users or loads of AC 230/400V, 50Hz and rated operating current 80A and below. It is mainly used in the household distribution box or other distribution line requiring protection.
