What is the Wago 821-505?
Control Signal Terminal Strips per § 9 EEG
Due to the requirements of § 9 of the Renewable Energy Act (EEG), operators of, e.g., PV systems or CHPs are obligated to make their feed-in systems remotely controllable for the energy operator or direct marketer. Grid fluctuations or failures caused by feed-in power levels that are too high are to be avoided in order to protect the electrical grid. In consultation and cooperation with various grid operators, these Control Signal Terminal Strips were developed in order to create a uniform standard according to the valid TCRs, which is quick and easy for the system installer to install. These sets are essential for standard-compliant system design as a central connection point between the control unit and the supply system.
These sets are delivered ready for installation and without a DIN-rail for the end user. They are developed for the German energy market.
