50A SCT-013-000 Non-invasive AC Current Clamp Sensor

The SCT-013-000 50A Non-invasive AC Current Clamp Sensor is designed for accurate and safe measurement of AC currents up to 50 Amps. With a split-core design, this current transformer sensor simply clips around a live or neutral wire to measure electricity usage without direct contact. It outputs a small AC voltage proportional to the current and is terminated with a standard 3.5mm jack for easy connectivity.

What is a Current Transformer (CT) Sensor?

A CT sensor (current transformer) is widely used for measuring alternating current (AC). The SCT-013-000 split-core CT sensor is ideal for DIY energy monitoring projects, smart home power management, and professional applications. Its non-invasive design makes installation safe, as it clips directly onto the cable without requiring electrical rewiring or high-voltage work.
