The SCT013-000 is a 100A current transformer (CT) used for measuring alternating current.Its primary advantage is its non-invasive nature; you can clip it around a power line without disconnecting the circuit or touching high-voltage terminals. This makes it a favorite for “Smart Grid” projects, home energy monitors (like OpenEnergyMonitor), and industrial load sensing. It comes with a 1-meter lead and a standard 3.5mm audio jack for easy connectivity.
Key Features
Non-Invasive Safety: Clip-on design allows for installation on live wires without any electrical contact or power interruption.
Wide Range: Capable of measuring AC current from 0A all the way up to 100A.
Built-in Protection: Includes a built-in sampling resistor (on most models) or diode protection to prevent high voltage open-circuiting.
High Quality: Made with ferrite core material and flame-retardant UL94-V0 housing.
Standard Interface: 3.5mm audio plug output for quick connection to sensor shields.
