Why Choose the Lovato DM3TA0800 Split-Core Current Transformer?
The Lovato DM3TA0800 is a heavy-duty split-core current transformer designed for accurate current measurement in industrial switchboards, electrical distribution panels and energy-monitoring systems. Featuring an 800/5 A transformation ratio, it converts a primary current of up to 800 A into a standard 5 A secondary output for connection to compatible energy meters, ammeters, multifunction measuring instruments and power analysers.
Its split-core construction allows the transformer to be opened and installed around an existing cable or busbar without removing or rerouting the primary conductor. This makes the DM3TA0800 particularly suitable for retrofit metering projects, electrical system upgrades and existing installations where downtime and installation work must be kept to a minimum.
With a large 80 × 120 mm internal opening, the DM3TA0800 accommodates substantial cables and rectangular busbars commonly used in high-current distribution systems. Operating at 50–60 Hz, it provides a burden of 3 VA at accuracy class 0.5 and 7.5 VA at accuracy class 1, delivering dependable current measurement for demanding industrial applications.

Reliable Current Measurement for Existing Installations
Current transformers safely convert high primary currents into proportional low-current outputs suitable for electrical measuring instruments. The Lovato DM3TA0800 converts currents up to 800 A into a standard 5 A secondary output, allowing accurate monitoring without connecting instruments directly to the power circuit.
The split-core construction is especially valuable for retrofit applications. Once the electrical circuit has been safely isolated, the transformer can be opened and installed around an existing conductor, significantly reducing installation time compared with conventional solid-core current transformers.
Typical Applications
- Industrial switchboards and power-distribution panels.
- Energy meters and multifunction measuring instruments.
- Power analysers and electrical monitoring systems.
- Building energy-management systems.
- Industrial machinery and automation panels.
- Commercial electrical distribution installations.
- Power quality monitoring.
- Retrofit metering and energy-efficiency projects.
