The RM35UB3N30 voltage measurement and control relay monitors phase loss, absence of neutral, overvoltage and undervoltage between phases and between neutral on 3-phase supplies. It features a sealable cover to help protect the settings and a control status indicator LED. The RMUB3 most common applications are control for connection of moving equipment (site equipment, agricultural equipment, refrigerated trucks); control against reverse motor operation (lifting, handling, elevators, escalators, etc.); control of sensitive 3-phase supplies; emergency power supply switching in abnormal condition.
