Main features - Reduced size to meet the most harsh applications - 0.5 1 3 class, currents from 1 A to 4000 A (in 4 models) - 2 to 6 bus-bar isolated fixing screws - Double screw terminals (up to 8-wire connections) Applications The new current transformers and split-core current transformer with bus-bar mounting facility from Carlo Gavazzi can be connected with all the existing wire terminals and can be installed either in DIN-rails or directly on panels. In addition, the CTD devices avoid any output overvoltage, during the maintenance and installation procedures, bridging the secondary without changing the connections.
