Non-Invasive AC Current Transformer 100A 50mA
£7.99
19 in stock
Overview
This non-invasive AC current transformer is designed for non-contact measurement of AC current up to 100 A. It provides a 50 mA proportional current output with a 1:2000 turns ratio, making it suitable for energy monitoring, load detection, and integration with compatible metering devices.
The split-core style design allows installation without disconnecting the conductor, while providing galvanic isolation between the measured circuit and monitoring equipment. It is intended for use in 50/60 Hz AC systems.
