200A/50mA Current Transformer YHDC SCT-024 – 24mm Opening


141 in stock

Warranty: 90 Days


These YHDC current transformers can measure current up to 200A, and fit around wires that are up to 24mm in diameter. They have custom 3.5mm jacks which plug directly into our power meters. A TVS diode is built in for safety, and to prevent open circuiting. The output is 50mA, when the current is 200A (the picture shows a previous version of the CT).

These will fit around 200A aluminum service mains wires. Copper mains are usually not as large.

If you need to measure more than 130A sustained, our 6 channel meters should not be used with these CTs. The Split Single Phase meter would be a better option.

Please note: We previously sold a 100mA output version of this CT.  It should not be used with the 6 channel meter if measuring over 66A. It should not be used with the Split Single Phase meter if measuring over 130A.
