Why Choose the Lovato DM2TA1250 1250/5 A Split-Core Current Transformer?
The Lovato DM2TA1250 is a split-core current transformer designed for high-current electrical measurement and monitoring applications. With a rated primary current of 1250 A and a standard 5 A secondary output, it provides a 1250/5 A transformation ratio for compatible energy meters, power analysers, ammeters and electrical monitoring equipment.
Its key advantage is the split-core construction, which allows the transformer to be installed around an existing conductor without disconnecting or removing the primary cable or busbar. This makes the DM2TA1250 particularly useful for retrofit energy-monitoring projects, existing switchboards and installations where minimising disruption during CT installation is important.
Designed to accommodate conductors and busbars within an approximately 80 × 80 mm window, the DM2TA1250 is suitable for large electrical distribution systems carrying substantial loads. The standard 5 A secondary enables straightforward integration with compatible instrumentation for current measurement, energy metering, load analysis and power monitoring.

Flexible High-Current Measurement with a Split-Core CT
A current transformer converts the high current flowing through a primary conductor into a proportional secondary current that can be measured safely by compatible instrumentation. With the DM2TA1250, a rated primary current of 1250 A corresponds to a standard 5 A secondary current, enabling energy meters, power analysers and other compatible devices to monitor high-current circuits indirectly.
The split-core design is particularly valuable when adding metering to an existing electrical installation. Instead of disconnecting a large cable or removing a busbar to pass it through a closed transformer core, the DM2TA1250 can be opened and positioned around the existing conductor. This makes it a practical choice for retrofit energy management, sub-metering and power-monitoring projects in established switchboards.
Typical Applications
- High-current energy metering installations.
- Industrial switchboards and distribution panels.
- Commercial building energy monitoring.
- Retrofit electrical metering projects.
- Power analyser current inputs.
- Large busbar current measurement.
- Electrical load and consumption analysis.
- Sub-metering and energy management systems.
