    LEM ATO-50-B333-D16 Split-Core Current Transformer

     

    LEM ATO-50-B333-D16 Product Overview

    The ATO-50-B333-D16 is a split-core current transformer from LEM's ATO series, designed for non-invasive AC current measurement with galvanic isolation between the primary and secondary circuits . It is specifically suited for smart grid applications, meeting IEC 61869 standards for ratio error and phase displacement .

    This model is rated for 50A primary current with a 333mV voltage output. The split-core design allows installation on insulated conductors without interrupting power supply, featuring a 16mm aperture and 1m output cable .
