Why Choose the Lovato DM0TW0010 10/5 A Wound Primary Current Transformer?
The Lovato DM0TW0010 is a wound primary current transformer designed for accurate current measurement in low-current electrical circuits. With a primary current rating of 10 A and a standard 5 A secondary output, it provides the current transformation required for compatible ammeters, energy meters, power analysers and protection or monitoring equipment.
Unlike a conventional solid-core current transformer where the primary conductor passes through the transformer aperture, the DM0TW0010 uses a wound primary construction. This makes it particularly suitable for lower primary current ratings where a defined 10/5 A transformation ratio is required without arranging multiple conductor turns through a conventional current transformer.
The DM0TW0010 provides an accuracy burden of 3.75 VA for Class 0.5 and 3.75 VA for Class 1. Its standard 5 A secondary makes it suitable for integration with a wide range of compatible Lovato and third-party electrical measuring instruments designed for current transformer inputs.

Accurate Low-Current Measurement with a Wound Primary CT
A current transformer reduces the current flowing in an electrical circuit to a proportional secondary current that can be safely measured by compatible instrumentation. The 10/5 A ratio of the DM0TW0010 means that a nominal primary current of 10 A corresponds to a 5 A secondary current, allowing suitable measuring equipment to monitor the primary circuit indirectly.
Wound primary current transformers are particularly useful at low primary current ratings because the primary winding is incorporated into the transformer rather than relying on a high-current conductor passing through an aperture. The Lovato DM0TW0010 therefore provides a practical solution for low-current metering, power analysis and electrical monitoring applications requiring a standard 5 A CT secondary.
Typical Applications
- Low-current electrical measurement.
- Energy meter current inputs.
- Power analyser installations.
- Panel-mounted ammeters and measuring instruments.
- Industrial electrical distribution panels.
- Commercial building energy monitoring.
- Machine and equipment current monitoring.
- Electrical load and consumption analysis.
