Customisation Services

Product Features:
  • Toroidal design.
  • Supplied with 24" insulated secondary leads, terminated with crimped ring connectors.
  • Suitable for use with bare (uninsulated) primary conductor in circuits up to 600 V (4 KV Hi pot); or at higher voltages when a suitably insulated conductor is used.
  • All units have 5 A secondary for use with standard AC ammeters with 5 A movements.
  • Two hole mounting bracket on all models.
  • UL E227616 volume #1 file number X0DW2.
Application Data:
  • To obtain current measurement:
    • Pass the wire carrying the current to be measured through the window of the CT transformer (acting as a primary winding).
    • Connect the CT secondary to an ammeter with a 5 A movement.
  • For higher accuracy or higher VA burden rating:
    • Choose a CT with a primary which is a multiple of the required primary rating and which has the accuracy or VA burden you require.
    • Loop the wire carrying the current to be measured through the window a number of times equal to the multiple. This "winding" will reduce the ratio back to required primary rating.
