CK20 current transformer - TENSE

Product description:
The CK20 series current transformers are used for indirect alternating current measurement in low-voltage electrical circuits. They can be used to supply ammeters, power meters, multimeters, and as inputs for protective relays and monitoring devices.

The transformer enables safe and accurate measurement of high currents thanks to the standardized 5 A secondary current.
