    LEM ATO-50-B333-D16/SP1 Split-Core Current Transformer

     

    LEM ATO-50-B333-D16/SP1 Product Overview

    The ATO-50-B333-D16/SP1 is a split-core (non-invasive) current transformer from LEM's ATO series, designed for electronic measurement of AC waveform current with galvanic isolation between the primary circuit (power) and the secondary circuit (measurement) . It is an ideal current transformer for Smart Grid applications, where ratio error and phase displacement are fully tested in accordance with IEC 61869 standards .

    This model is rated for 50A primary current with a 333mV voltage output at rated current. The split-core design allows installation on insulated conductors without interrupting power supply, featuring a 16mm sensing aperture and 1m output cable. The "SP1" suffix indicates this is a specific version of the ATO-50-B333-D16 model.
