The grid and system protection NA003 from TELE has already been longer certified for the VDE-AR-N 4110: 2018-11 – “Technical Connection Rules for Medium-Voltage” (TAR medium voltage). Thus, the device can be used in medium voltage networks up to 60kV, as they occur, for example, in the context of combined heat and power plants (CHPU). Now, TELE has received an additional certification, which makes it possible to use the NA003 as a higher-level uncoupling protection, if no Q-U protection is required, or this requirement is technically solved otherwise.
