    LEM ATO-10-B333-D10 ATO Series Split-Core Current Transformer


    10A Rated Current x 333mV Voltage Output — Class 1 Accuracy for Smart Grid and Energy Metering

     

    LEM ATO-10-B333-D10 Product Overview

    The ATO-10-B333-D10 is a split-core AC current transformer from LEM's ATO Series, designed for the electronic measurement of AC waveforms with galvanic isolation between the primary and secondary circuits. This 10 A nominal version features a 333 mV voltage output at rated current and a 10 mm sensing aperture, enabling installation on insulated conductors without service interruption.

    Rated for 10 A nominal, it outputs 333 mV with Class 1 accuracy (IEC 61869-2) and high linearity. Turns ratio is 1:1000. Bandwidth is 50 Hz / 60 Hz. Supply voltage is self-powered. Mass is approximately 81 g and operating temperature is -10 °C to +55 °C. Insulation test voltage is rated for 600 V CAT III PD2, basic insulation.

    LEM ATO-10-B333-D10 Key Advantages

    The ATO-10-B333-D10 employs air-core technology, delivering Class 1 accuracy while providing galvanic isolation between primary and secondary circuits. The 10 A range provides direct measurement capability for low-current circuits, while the self-powered design eliminates the need for external power supplies and simplifies installation. The 10 mm aperture accommodates standard insulated conductors and the split-core design with plastic tie slot enables quick, non-intrusive installation without service interruption. The 600 V CAT III insulation ensures safe operation in distribution panels with basic insulation protection.

     

    LEM ATO-10-B333-D10 Typical Applications

    Hybrid inverter (home energy storage)
    Power metering: current measurement for active power calculation
    Building sub-metering: energy efficiency monitoring, consumption analysis and cost allocation
    Power quality monitoring: electrical loads and distribution system equipment
    Distributed measurement systems
    Condition monitoring (motor loads such as conveyors and pumps)

     

    Why Choose the LEM ATO-10-B333-D10?

    The ATO-10-B333-D10 combines 10 A nominal capacity with 333 mV voltage output and IEC 61869-2 Class 1 accuracy in a compact split-core package with self-powered operation. Manufactured by LEM, it delivers stable, accurate, and safe AC current measurement for industrial and smart grid applications. The 1 m output cable with wire leads simplifies integration, and the optional DIN rail adapter offers flexible mounting options. This model offers a cost-effective solution for non-invasive current monitoring where voltage output is preferred over current output, making it ideal for direct connection to PLCs, energy meters, and data acquisition systems.
