    LEM ATO-30-B333-D10 Split-Core Current Transformer

     

    LEM ATO-30-B333-D10 Product Overview

    The ATO-30-B333-D10 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 30A 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 10mm sensing aperture and 1m output cable.
