£161.61
The Lovato DM2TA1000 is a robust and reliable 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 the primary conductor. This makes the DM2TA1000 particularly suitable for retrofit metering projects, energy-management upgrades and existing electrical installations where reducing modification work and system downtime is important.
With a large 80 × 80 mm internal opening, the DM2TA1000 accommodates substantial cables and rectangular busbars commonly used in high-current power-distribution equipment. It operates at 50/60 Hz and provides a rated burden of 5 VA at accuracy class 0.5 and 10 VA at accuracy class 1, supporting dependable electrical measurement in demanding commercial and industrial environments.
Current transformers provide a safe and practical method of measuring high electrical currents by converting the primary current into a proportional secondary signal for compatible instrumentation. The Lovato DM2TA1000 converts a primary current of up to 1000 A into a standard 5 A secondary output, enabling meters and monitoring devices to measure electrical loads without being connected directly to the high-current circuit.
The split-core construction is particularly valuable when adding metering equipment to an existing installation. Once the circuit has been safely isolated, the transformer can be opened, positioned around the cable or busbar and securely closed without removing or rerouting the primary conductor. This helps reduce installation labour and disruption while supporting effective energy management and electrical system analysis.

The DM2TA1000 is used to measure high electrical currents in switchboards, distribution panels and energy-monitoring systems. It converts a primary current of up to 1000 A into a standard 5 A secondary output.
The transformer has a 1000/5 A transformation ratio, meaning that a nominal primary current of 1000 A corresponds to a 5 A secondary current.
Yes. Its split-core construction allows it to be opened and fitted around an existing cable or busbar after the electrical circuit has been safely isolated.
The transformer has an 80 × 80 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 0.5 and 10 VA at accuracy class 1, depending on the connected measuring circuit.
Lovato Electric current transformers are widely used by panel builders, electrical contractors and industrial engineers to provide reliable current measurement, practical retrofit installation and dependable integration with modern energy-monitoring equipment.
