Description

Single phase current, voltage & power monitoring relay ??-163 is designed to protect (disconnect) the equipment (load) connected to it in the following cases: - exceeding the threshold value of the controlled parameter; - deviation of the mains voltage from the set values; - excess of the temperature of the contact group (85 °?). ??-163 can be used as: - power consumption limiting relay; - voltage relay; – current overload relay; - energy meter (indication of total, active, reactive power, current consumption and mains voltage). ??-163 is powered by the circuit that feeds the load. ??-163 displays the value of the parameters and the status of the relay using LED indicators and display.
