Woodward MRU4-2A0ABA MRU4 Voltage Relay 800V

Woodward MRU4-2A0ABA Voltage Relay  :  Door mounting, 8 digital inputs, 6 output relays, voltage measuring 800V, Modbus RTU / IEC 60870-5-103 / DNP3.0 RTU, RS485, Terminals

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.

Woodward MRU4-2A0ABA Voltage Relay  and other products in Interconnection / Mains Decoupling

During mains failures, DER (Distributed Energy Resources) should stay operated and connected to the grid to support decreasing mains voltage, by feeding reactive power. Woodward has developed various Intelligent Electronic Devices, which are in compliance with international grid requirements (Grid Codes), to avoid electrical or mechanical damage to the DER in these cases.

The following product lines offer the right Interconnection / Mains Decoupling products to you.
