Why Choose the Lovato DM3TA1000 Split-Core Current Transformer?
The Lovato DM3TA1000 is a heavy-duty split-core current transformer designed for accurate current measurement in industrial switchboards, electrical distribution panels and energy-monitoring systems. Featuring a 1000/5 A transformation ratio, it converts a primary current of up to 1000 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 DM3TA1000 particularly suitable for retrofit metering projects, electrical system upgrades and operational installations where reducing panel modifications and system downtime is important.
With a large 80 × 120 mm internal opening, the DM3TA1000 accommodates substantial conductors and rectangular busbars commonly used in high-current power-distribution equipment. It provides a rated secondary apparent power of 10 VA at accuracy class 1, supporting dependable current measurement in demanding commercial and industrial environments.

Reliable Current Measurement for High-Current Systems
Current transformers provide a safe method of measuring high electrical currents by converting the primary current into a proportional lower-current output for compatible instrumentation. The Lovato DM3TA1000 converts a primary current of up to 1000 A into a standard 5 A secondary signal, enabling meters and monitoring equipment to measure electrical loads without being connected directly to the high-current circuit.
The split-core design is particularly useful when adding metering equipment to an existing electrical installation. Once the electrical system has been safely isolated, the transformer can be opened, positioned around the conductor and securely closed without removing the cable or busbar. This helps reduce installation labour and panel modifications while supporting effective energy management and electrical-system analysis.
Typical Applications
- Industrial switchboards and high-current distribution panels.
- Energy meters and multifunction measuring instruments.
- Power analysers and electrical monitoring systems.
- Building and facility energy-management systems.
- Electrical load and maximum-demand monitoring.
- Industrial machinery and automation panels.
- Commercial power-distribution installations.
- Retrofit metering and energy-efficiency projects.
