Why Choose the Lovato DM3TA2000 2000/5 A Split-Core Current Transformer?
The Lovato DM3TA2000 is a split-core current transformer designed for high-current electrical metering and monitoring applications. With a rated primary current of 2000 A and a standard 5 A secondary output, it provides a 2000/5 A transformation ratio for compatible energy meters, power analysers, ammeters and other measuring equipment.
Its 80 × 120 mm conductor opening accommodates large busbars used in industrial and commercial power distribution systems. The split-core construction allows the transformer to be opened and fitted around an existing conductor, making the DM3TA2000 particularly useful for retrofit metering installations where disconnecting or removing a large busbar would be impractical.
Designed for 50–60 Hz systems, the DM3TA2000 provides 17 VA at Class 1 and supports continuous operation at up to 120% of rated primary current. A 720 V rated insulation voltage, Class E dry-type insulation, screw secondary terminals and IP30 protection provide a robust solution for professional high-current measurement.

High-Current Retrofit Measurement with a Split-Core CT
A current transformer converts a high primary current into a proportional secondary current suitable for compatible measuring instrumentation. With the DM3TA2000, a rated primary current of 2000 A corresponds to a 5 A secondary output, allowing energy meters and power analysers to monitor high-current circuits without carrying the full primary load current through the measuring device.
The split-core construction is especially advantageous when metering is being added to an existing installation. The DM3TA2000 can be opened and positioned around a suitable busbar or conductor rather than requiring the conductor to be passed through a closed transformer core. Its large 120 × 80 mm opening makes it particularly suitable for substantial busbar systems in industrial switchboards and commercial electrical distribution equipment.
Typical Applications
- High-current energy metering installations.
- Industrial switchboards and main distribution panels.
- Commercial building electrical distribution.
- Retrofit energy-monitoring projects.
- Power analyser current inputs.
- Large busbar current measurement.
- Electrical load and consumption analysis.
- Energy management and sub-metering systems.
