OUVR-1 Self-recovery Over-voltage and Under-voltage Protector

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≤1s; 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 CATALOG OUVR-1 Self-recovery Overvoltage and Undervoltage Protector
