CT Series - Current Transformer Indoor Toroidal

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 volts (5 KV hipot); or at higher voltages when a suitably insulated conductor is used.
  • All units have 5 amp secondary for use with standard A.C. ammeters with 5 amp movements.
  • Two hole mounting bracket on all models.
  • UL E227616 volume #1 file number X0DW2.
Application Data
To obtain current measurement:
  1. Pass the wire carrying the current to be measured through the window of the CT transformer (acting as a primary winding).
  2. Connect the CT secondary to an ammeter with a 5 amp movement.
For higher accuracy or higher VA burden rating:
  1. 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.
  2. 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 ration back to required primary rating.
    • Example: "A": To obtain an accuracy of 1.2% at 10 VA burden with a ration of 100:5, use a CT400A and loop 4 primary turns through the window.
    • Example: "B": To obtain a 25:5 ration, use a CT75A with 3 primary turns to yield 2% accuracy or a CT50A with 2 primary turns to yield 3.2% accuracy.
