Overvoltage and undervoltage protector, 3P+N, 63A, 230V self-recovery&#x4;&#x4;Features:&#x4;Self-recovery overvoltage and undervoltage protector is used to protect electrical equipment from overvoltages or undervoltages.&#x4;Automatic protection against voltage fluctuations is suitable for AC 230V circuits with a rated operating current of max 63A.&#x4;When overvoltage or undervoltage problems occur in the circuit, the protector quickly and safely breaks&#x4;the circuit, and when the circuit voltage returns to normal, it automatically turns on the power.&#x4;Compact design, reliable operation, easy installation on a DIN rail.&#x4;With power and protection function LED indicators (red, green).&#x4;It is mainly sed in household distribution boxes or other distribution lines that requiring protection.&#x4;Main functions:&#x4;1. Overvoltage protection.&#x4;2. Undervoltage protection.&#x4;3. Automatic recovery.&#x4;Note: The inclination of installing surface cannot exceed 5°.&#x4;&#x4;Technical specifications:&#x4;Rated voltage: AC 230V.&#x4;Current: 63 A.&#x4;Frequency: 50/60Hz.&#x4;Overvoltage operating cutoff value: AC 275V ±5V.&#x4;Undervoltage operating cutoff value: AC 165V ±5V.&#x4;Overvoltage recovery value: AC 255V ±5V.&#x4;Undervoltage recovery value: AC 185V ±5V.&#x4;Response time: < /= 1s.&#x4;Recovery time: < /=60s.&#x4;Poles: 3P+N.&#x4;Power consumption: < 2W.&#x4;Electrical life: > 50000 times.&#x4;Installation: on DIN rail (35mm).&#x4;Operating temperature: from -35°C to +70°C.&#x4;Relative humidity (at 40°C):
