Description and Application

The transformer converts a high primary current (up to 1500 A) into a standard and safe secondary current of 5 A, intended for the following purposes:

• Measuring Instruments

• Meters and Monitoring Systems

• Automation Devices

• Protection and Control Circuits

It provides accurate measurement of sinusoidal alternating current and, thanks to its accuracy class of 0.5S, is also suitable for commercial meters, consumption monitoring, and energy audits. Installation is quick - the transformer is simply slipped onto a 100 mm diameter busbar.
