Depending on application, the logical unit can be chosen between three possible width options: 36TE, 46TE or 56TE. The device consists of set of basic functional modules i.e. power and CPU module and set of extending modules which depends on specific need: current and voltage measuring module, binary inputs modules, relay outputs modules, analog inputs module, communication modules. Device construction, huge set of extension modules, rich library of protection and control functions allows to provide complex control of each power object which has to be protected.
