Description
The SCT-013-060 is a split-core AC current transformer designed for non-invasive current measurement in energy monitoring, load diagnostics, and equipment protection. As a voltage-output variant in the YHDC SCT-013 family, it includes an internal sampling resistor, delivering a direct 0–1V AC output proportional to the primary current—no external burden resistor is required for basic operation . The clamp-on design allows installation around an existing insulated conductor without cutting or disconnecting the wire, making it suitable for retrofitting into live electrical installations.
This model is rated for 60A AC (RMS) input with a maximum input of approximately 75A . It is commonly used for monitoring AC motors, lighting equipment, air compressors, and HVAC systems . The 1-meter cable terminates in a standard 3.5mm audio plug, with the tip and sleeve carrying the signal.
Accuracy note: Several distributor listings specify ±1% accuracy with linearity ≤0.2% for the SCT-013-060 . However, the manufacturer’s general SCT-013 datasheet specifies non-linearity of ±3% (10%–120% of rated input) . The ±1% figure is widely published for this specific model, but buyers should verify the accuracy guarantee with their supplier. For critical applications, calibration against a known reference load is recommended.
