CK20 Current Transformer - TENSE

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

The transformer enables safe and accurate measurement of high currents using a standardized 5 A secondary.
