SCT-013 30A Split-Core AC Current Sensor

The SCT-013 Non-Invasive Current Sensor is a split-core current transformer designed for measuring AC current up to 30A without direct electrical contact. It converts the measured current into a proportional voltage output (30A:1V), enabling safe monitoring of electrical loads. The ferrite-core design provides stable measurement performance with strong electrical insulation and 6000V dielectric strength. This sensor can be clipped directly around a live or neutral wire, eliminating the need to cut or modify the circuit. It is widely used in energy monitoring systems, smart power meters, and building electricity consumption measurement projects.
