CT - AC Current Transformers

To create part number, replace XXX with Primary current value (input) and add zero in front of current values less than 3 digits. Then replace Y with secondary (output) value of either 1Amp or 5Amp. One CT is required for each phase.




FEATURES

  • The primary winding is either a cable or busbar that is insulated for voltage application.
  • To be used with Watt, Var, Watt/Var, Watt/Watt-Hour Transducers, Meters and Relays.
  • The base can be mounted either in line with CT or transversely.
