MRU4 voltage and frequency protection
The MRU4 is a highly precise and reliable protection device with the latest dual-core processor technology and extremely simple operation.
The MRU4 protects electrical equipment from impermissible voltage drops, such as short circuits in the mains, and from impermissibly high voltages, such as those caused by load shedding or generator voltage regulator faults.
Due to its compact design, the MRU4 is ideally suited for installation in the low-voltage niche of compact SF6-insulated medium-voltage systems.
The protective functions of the MRU4 have been enhanced to meet the requirements of VDE-AR-N-4110/4120:2018.
