Model: RED521 1MRK002003-BA

The RED 521 is the digital successor to the rads and REB 103 analog relays and has been installed in more than 10,000 zones over a period of 35 years. These relays show an impressive track record with no erroneous operation, RED521 1MRK002003-BA due to the incorrect functionality of the relays. The design of the RED 521 continues this tradition. In addition, it has been tested in the same high-current laboratory to verify its design. In addition, the terminal has performed well in multiple evaluation tests at the customer's test facility.

The RED 521 terminal belongs to the ABB 500 series of protection and control terminals. More than 25,000 terminals from this product family have been successfully installed in power grids around the world.
