AC Current Clamp Sensor SCT-013-100 (100A)

The AC Current Clamp Sensor SCT-013-100 (100A) is a non-invasive split-core current transformer (CT) designed for safely measuring AC current up to 100A without disconnecting or cutting the electrical wiring. By simply clamping around a single live conductor, it provides an isolated output proportional to the measured current, making it ideal for energy monitoring, smart metering, power analysis, and IoT-based electrical monitoring systems. Compatible with Arduino, ESP32, STM32, Raspberry Pi (with external ADC if required), and other microcontroller platforms, the SCT-013-100 Current Clamp Sensor is available at Directronics and is ideal for students, hobbyists, makers, educators, and professional engineers.

Note:

Product images are for illustration purposes only. Actual enclosure color, cable length, connector type, and output configuration may vary depending on the manufacturing batch. The SCT-013-100 measures AC current only and cannot measure DC current. Clamp the sensor around only one conductor (live or neutral)—clamping around both conductors simultaneously will result in little or no output due to magnetic field cancellation. Some variants require an external burden resistor or signal conditioning circuit before interfacing with a microcontroller ADC. Proper calibration is recommended for accurate current and power measurements. (Directronics)
