Description
A Voltage Monitoring Relay (VMR) is a protective device designed to monitor the voltage levels in an electrical system and automatically disconnect or activate certain actions when the voltage goes outside preset limits. These relays are typically used in both industrial and residential settings to protect equipment from potential damage caused by voltage fluctuations, such as under-voltage or over-voltage conditions.
