Measuring Current Transformer CK20 - TENSE

Product description:
The CK20 series current transformer is designed for indirect AC current measurements in low-voltage electrical circuits. It is used to power ammeters, power meters, and multimeters, or as an input for protective relays and monitoring devices.

The transformer allows safe and accurate measurement of large currents using a standardized 5 A secondary current.
