MRA4 Directional Feeder Protection

The MRA4 is a high precision and reliable protection and control relay. 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.

In fact, the MRA4 is our interconnection and mains decoupling expert.

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 is usable for each HighPROTEC device and free of charge.
