ZHRV1 Series Three Phase AC LED Voltage Monitoring Relay
General:
ZHRV1 series relays adopt digital circuit arithmetic operation systems which carried on by singlechip, with high precision; applied in the circuit of AC 50/60Hz 220V, 230V, 240V, 380V, 400V, 415V for overvoltage, undervoltage, phase failure, phase sequence, three phase asymmetry monitoring and PTC temperature, load side protection; in the circuit of three phase four wire, relays which have no phase sequence monitoring function can be used to protect single phase and two phase circuit. They are widely used for industrial control systems, capacitor of power compensation, switch boards, air condition systems, motor etc.
Conform to: IEC60947 5 1 standard
Opeating conditions:
1. Altitude: ≤2000m
2. Ambient temperature: -5°C+40°C, average value within 24h shall not exceed 40°C.
3. Air conditions: relative humidity shall not exceed 50% at max temperature +40°C.
higher relative humidity is allowable under lower temperature, for example, relative humidity can reach 90% at +20°C, special measures should be taken to occurrence of dew.
4. Pollution grade: 3
5 Installation category: Ⅱ
6 Housing protection class IP20
