Product Features
• Torodial design.
• Supplied with 24" insulated secondary leads, terminated with crimped ring connectors.
• Suitable for use with bare (un insulated) 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.

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 A 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 ratio back to the primary rating.
