SINOTIMER STVP-930 63A 80A 380V 3 Phase Auto-recovery Protective Device Self Reconnect Surge Voltage Protector DIN Rail

Description STVP series SINOTIMER brand automatic over voltage and under voltage protector is suitable for three phase AC 380V 50 60Hz rated working current 80A Its main feature is when the circuit has over voltage or under voltage problems the product can cut off the power supply instantaneously to protect the electrical equipment from being damaged besides the protector can automatically turn on the power supply when the circuit voltage returns to the normal Features 1 Over voltage protection2 Under voltage protection3 Zero line break protection4 Phase failure protection5 Phase order protection reverse phase protection Opition 6 Three phase voltage unbalance protectionParameters Rated voltage 3 phase 4 wires 230V 400VAC 50 60HzRated current 63A 80APower on time 2s System self test Delay time after power on 40sOvervoltage protection value range 280V±5VOvervoltage recovery value range 250V±5VUndervoltage protection value range 170V±5VUndervoltage recovery value range 185V±5VOV and UV protection action time 0 1s3 phases volt unbalance protection value 35 default or customised3 phases volt unbalance protection action time 1sPower off protection time 0 1sFailure recovery delay time 40sFaulty Signal LEDGrounding system TT TN S TN C SInstallation DIN railElectrical isolation strength 2000VAC pulse 2 5KV 1 2 50μSTemperature 20⁰C 50⁰CHumidity 85 Altitude ≤2000 mRemark 1 The default protection voltage imbalance rate is 35 and the recovery val
