SCT 013-000 Current Transformer Sensor – 100A AC Non-Invasive CT Clamp

The SCT 013-000 Current Transformer (CT) Sensor is a non-invasive clamp-style AC current sensor designed to measure up to 100A AC safely and accurately. Because it clips around the wire instead of connecting directly, it provides an easy and safe way to monitor current without cutting or interfering with the electrical circuit.

This CT sensor outputs an analog voltage proportional to the current flowing through the wire, making it ideal for energy monitoring systems, smart meters, IoT projects, Arduino setups, ESP32 monitoring, home automation, and industrial power analysis.

It is widely used with open-source platforms such as Arduino, ESP8266, ESP32, Raspberry Pi, and energy monitoring libraries like OpenEnergyMonitor.

Key Features:

• Non-invasive clip-on current transformer

• Measures up to 100A AC

• Safe, isolated output (no direct electrical connection)

• High accuracy and stable performance

• Easy to interface with Arduino & microcontrollers

• Ideal for energy meters, power monitoring, and automation systems

• Strong build quality with a secure locking mechanism
