This is an AC current measuring sensor featuring CT technology, CT stands for current transformer, a transformer unit split in two half like a clamp for measuring alternating current source.

Non-invasive AC Current Sensor can measure a load up to 30 Amps AC source, simply clamp the current sensor on the live wire or neutral wire. The sensor measure the amount of current flowing through the wire. The output is a small AC signal which can be further use for energy meter application or for over-current protection of AC devices. To facilitate the application need the sensor has 3.5mm jack on the output side.

Popular application of Non-invasive current sensor are like safe working on the high voltage electrical lines, protection of over current of the electrical device like AC motor, Air compressor.
