Lovato DM3TA0600 split-core current transformer with a 600/5 A transformation ratio, 80 x 120 mm opening, class 1 accuracy and 5 VA burden for industrial current measurement.
£170.59
The Lovato DM3TA0600 is a robust split-core current transformer designed for reliable current measurement in industrial switchboards, electrical distribution panels and energy-monitoring systems. Featuring a 600/5 A transformation ratio, it converts a primary current of up to 600 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 DM3TA0600 particularly suitable for retrofit metering projects, power-monitoring upgrades and established electrical installations where reducing modification work and operational disruption is important.
With a large 80 × 120 mm internal opening, the DM3TA0600 accommodates substantial cables and rectangular busbars commonly used in high-current distribution equipment. It operates at 50–60 Hz and provides a rated burden of 5 VA at accuracy class 1, supporting dependable current measurement in demanding commercial and industrial environments.
Current transformers provide a safe method of measuring high electrical currents by converting the primary current into a proportional secondary output for compatible instrumentation. The Lovato DM3TA0600 converts a primary current of up to 600 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 valuable when adding metering equipment to an existing installation. Once the electrical system has been safely isolated, the transformer can be opened, positioned around the cable or busbar and securely closed without removing the primary conductor. This helps reduce installation labour and panel modifications while supporting effective energy management and electrical system analysis.

The DM3TA0600 is used to measure electrical currents in switchboards, distribution panels and energy-monitoring systems. It converts a primary current of up to 600 A into a standard 5 A secondary output.
The transformer has a 600/5 A transformation ratio, meaning that a nominal primary current of 600 A corresponds to a 5 A secondary current.
Yes. Its split-core construction allows the transformer to be opened and fitted around an existing cable or busbar after the electrical system has been safely isolated.
The transformer has a large 80 × 120 mm internal opening, making it suitable for substantial cables and rectangular busbars within those dimensions.
The transformer provides a rated burden of 5 VA at accuracy class 1 for compatible current-measurement and energy-monitoring equipment.
Lovato Electric current transformers are used by panel builders, electrical contractors and industrial engineers to provide dependable current measurement, practical retrofit installation and reliable integration with modern energy-monitoring equipment.
