Low-voltage surge arrester / type 2 - CT
The stepped design of the CT fine overvoltage protector is specially aimed at protecting data processing, instrumentation and telecommunication systems from atmospheric or industrial transient overvoltages.The equipment consists of a base completed with a plug containing the impedance isolating elements (spark-gaps and diodes) as well as a fine protection stage.
It is possible to disconnect the plug from the base without interrupting the circuit
