This device can be of use with 3, Phase over and under electrical potential and more current protection along with real time voltage and current monitoring. Quick response with 0. 1 second cut you can, Off time set the response time ranging 0. 1, 30sec. This voltage guard identifies and outings on voltage assymetry with auto recuperation capability once the evenness is re, Established. Phase imbalance protection should there be difference between 3, The device, Phase voltage will cut off. You have the option to customize this based on your need and requirement ranging 20, 99v. Phase loss protection this feature is a must if this device is formulated to function as industrial purpose where all phase presence is required. In case of even one phase lost the device will cut off the power supply.
