ZHRV5-45 Voltage control relay
Categories Voltage Control Relay Rated supply voltage 3-phase 3-wire 220V~450V AC Rated supply frequency 50/60Hz Phase failure and phase sequence ≤0.5s Measurement accuracy ±1% Data storage time 10 years Accumulated timing error ≤0.001% Contact configuration capacity(A) 10A IP Class IP20 Altitude ≤2000m Use category AC-15 Update Time 2021-06-22Detail Information
Used in air conditioning units, elevator machine room, pumps, fans and other motor control applications, as protection of over-voltage, under voltage, phase failure, phase sequence and phase unbalance. When the power supply is abnormal, turn off power supply to protect the equipment.
Built-in microprocessors, true RMS voltage measurement, voltage measurement accuracy≤1%. Measuring frequency 45Hz~65Hz,knob setting, LCD displays voltage and fault information,protection can be turned on or off.Check 3-phase voltage value by button,with counting and timing function.Record number and time of useing devices.DIN rail mounting.Function DiagramDimensionsCompany
