Summation current transformer for primary nominal currents of 5 A or 1 A, secondary nominal current 5 A or 1 A (optional 2 A), accuracy class 0.5 and 1 for the connection of 2 main CTs.
It is possible to connect main CTs with different nominal transmission ratios.
The nominal currents of each main CT have to be stated, when the order is placed. (The maximum ratio of the primary current of a main CT to the sum of the primary currents of all main CTs must not exceed 1:8).
The article numbers of these special CTs are different to them mentioned below.
