MRU3-1 Voltage Relay
The voltage supervision relay MRU3-1 protects electrical power generators, consumers or operating components generally against over- or undervoltages.
Among other applications the relay can be used for detection of over- or undervoltages in power generating plants and energy supply systems.
to protect generators against critical overvoltages in case of defective voltage regulators
as undervoltage protection for motors
