MRA4-Family
HighPROTEC MRA4
Directional Feeder Protection
The MRA4 is a high precision and reliable protection and control relay for feeder, grid and generator applications. The intuitive setting concept with plausibility test enables reliable and time optimized configuration of the extensive protection function to a variety of applications such as incoming or outgoing feeder protection, network protection and generator protection. The implemented switchgear management guaranties an efficient and safe control and supervision. The device is a bench mark in flexibility and usability and offers various communication options. The hardware is designed for all nominal values in combination with protection and control functionality. The parameterizing and analyzing software Smart view SE is usable for each HighPROTEC device and free of charge.

MRI4-Family
HighPROTEC MRI4
Feeder Protection
The MRI4 is a feeder protection relay that provides precise and reliable protective functions and is very easy to operate. The MRI4 provides a number of three phase protection elements to safeguard against overcurrent, short-circuit and earth fault, all with inverse time (INV) and definite time (DEFT) tripping characteristics. The MRI4 is also ideal for the protection of isolated, resonant, resistive and solidly earthed neutral systems. It is designed to be used in both radial networks and single fed open ring main systems. It can also serve as backup protection for differential protection systems on generators, transformers, bus bars and electrical lines. For overhead line protection the MRI4 is also available with an optional auto reclosing function. The protection functions of the MRI4 have been adapted to comply with the requirements of the VDE‑AR‑N‑4110:2018.
