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.

The cable / line differential protection relay MCDLV4 is designed to be used pairwise for protecting cables and lines up to 24 km. There can even be an in-zone transformer within the line to be protected. In addition, it comes with a very comprehensive protection package like phase, restricted earth fault, inrush detection, and monitoring functions including grid interconnection and control functionality up to 6 switchgears.
The intuitive operating concept with plausibility checks and extensive commissioning functions such as the built-in fault simulator allows a safe and time-optimized maintenance and commissioning. The parameter setting and evaluation software Smart view can be used consistently across the entire family of devices.

Smart view is even capable of monitoring the remote MCDLV4 via the protection communication interface between the two MCDLV4 devices. The MCDLV4 is available in 576 variants, that cover all combinations of properties that you might need or not need for your application.
