Woodward MRU4-Family HIGHPROTEC MRU4 Voltage Relay

Woodward HIGHPROTEC MRU4 Relay : The voltage protection relay MRU4 provides precise and reliable protective functions and is very easy to operate. It is designed to protect electrical equipment from dangerous voltage fluctuations. For example protection against under voltages caused by mains shortcircuits, or overvoltages due to load shedding or failure of a generator voltage controller.

Its compact design makes the MRU4 ideal for installation within the LV terminal compartments of compact SF6-insulated MV systems. The protection functions of the MRU4 have been adapted to comply with the requirements of the VDE AR N 4110:2018. The MRU4 is available in 48 variants, that cover all combinations of properties that you might need or not need for your application. Each variant is uniquely specified by a typecode of form MRU4-2xxxxx (i.e. 5 digits/letters following the ‘-2’). Check the Order Form (depicted below, or in the brochure DOK-FLY-MRU4-2E or in the user manual MRU4-3.6-EN-MAN) for a complete overview.
