Features:
Screwless CAGE CLAMP ® connection technology
Several mounting options available
Vibration- and shock-resistant
High mechanical retention forces
High current-carrying capacity
Continuous overload of 120 % the nominal primary current
Low-voltage current transformer for operating voltages up to max. 1.2 kV
For 690 V power networks
UL recognized components
