<!--.STYLE1 {font-size: 14px;font-weight: bold;}.STYLE2 {font-size: 16px}--> This three phase voltage and current protector is made of flames resistant material, high strength and wear resistance, with fine durability. Dual digital displays and with large fonts design, real time display of current and voltage, if the voltage and current are not correct you can calibrate it manually. Two working modes design, with voltage balance, automatic power off, automatic reset, and the reset time and action time are adjustable. With over-voltage, under-voltage, over-current, short circuit, overload and wires protecting functions.Features:Premium Material:The housing is made of flames resistant material, high strength and wear resistance, with fine durability.Digital Display:Dual digital displays and with large fonts design, real time display of current and voltage, if the voltage and current are not correct you can calibrate it manually.Two Working Modes Design:With Synchronous (SYN) and Asynchronous (ASY) mode for you to adjust, easy to satisfy with your needs.Synchronous (SYN) Mode:Three phase relay open close at same time, can be used as three phase protector.Asynchronous (ASY) Mode:Three phase relay work separately, can be used as three individual single phase protectors.Multiple Protections Design:With over-voltage, under-voltage, over-current, short circuit, overload and wires protecting functions.Multifunctional Design:With voltage balance, reset time adjustable and action time adjustable function.Automatic Power Off:It can cut off the power supplies instantaneously when the line has overvoltage or undervoltage overcurrent faulty, so as to protects the electrical equipment from being damaged. Overload automatic power off, normal power supplys within specified power.Automatic Reset:When it is ASY mode, no phase sequence and voltage unbalance protect, it will automatic reset to prevents power failure for a long time and quick response to prevents the trouble caused by overvoltage and undervoltage.Specifications:Name: Voltage and Current ProtectorMaterial: plasticsType:63A, 100A(optional)Power on delay time: 1s-500sOvervoltage protecting ranges: 230V-300VUndervoltage protecting ranges: 140V-210VUnder-voltage recovery value: 145V-215VThree phase voltage unbalance value: 20V-99VThree phase voltage unbalance recovery value: 15V-94VOver-current protecting value: 3A-63A-OFF, 3A-100A-OFF(according to your selection)Item size:63A: 90 * 66 * 90mm / 3.54 * 2.59 * 3.94in100A: 90 * 66 * 101mm / 3.54 * 2.59 * 3.97inPackage size: 130 * 110 * 80mm / 5.12 * 4.33 * 3.15inPackage weight:63A: 400g / 0.88lb100A: 500g / 1.10lbPacking List:1 * Voltage and Current Protector Drop Shipping Service. 1.
