MK6VAsMK6Vs Overvoltage and Undervoltage Protector

Product Details

General

Voltage and current display relay is a microprocessor-based voltage monitoring device for single-phase AC networks to

protect electrical equipment from surge voltage.The device analyzes the main voltage and displays its current value on a digital indicator.Load is switched by electromagnetic relay.The user can set the current voltage value and delay time through the button. The value is stored in non-volatile memory.Aluminum wires and copper wires can be used for connection.

Application

Voltage and current display relay used in administrative,industrial and residential buildings and has the function of protecting single-phase lines:

●Undervoltageprotection;

·Overvoltageprotection;

●Workingundervoltmetermode;

●Overcurrent proteciton.
