The SIPROTEC 4 generator and motor protection relays, the 6UM61 and 6UM62, are specially designed to protect power generation systems, from small to large.  With their wide range of protection functions, the 6UM61 and 6UM62 can be used in any type of power plant – from the industrial power stations, through generation systems based on renewable energies, to the conventional steam power plants.  These relays can be deployed for the protection of motors and transformers as well.
