The relay type VHXm is a static under/over voltage relay used for detection of under voltage (or loss of voltage) or over voltage in the AC system. Relay is used for over voltage protection and supervision in distribution systems. Relay is also used for overvoltage / undervoltage protection of Generators, Motors and Transformers.
The relay is powered by a DC auxiliary supply. The relay has a built-in electromechanical output relay providing medium duty contacts. The output also has one red hand reset flag.
