The Lovato DM2TMA0250 is a split-core current transformer designed for accurate current measurement in electrical distribution, energy monitoring and industrial metering applications. Part of the Lovato DM2TMA current transformer series, it provides a 250/5 A transformation ratio, converting a primary current of up to 250 A into a standard 5 A secondary signal for compatible measuring instruments.
Its split-core construction allows the transformer to be fitted around an existing conductor without disconnecting or removing the cable or busbar. This makes the DM2TMA0250 particularly useful for retrofit energy monitoring, electrical panel upgrades and installations where interrupting the existing power wiring would be inconvenient.
With an approximately 80 × 80 mm external format, the DM2TMA0250 combines practical installation with dependable measurement performance. It is suitable for use with compatible Lovato energy meters, ammeters, power analysers and other instrumentation accepting a 5 A current-transformer secondary input.
Current transformers provide a proportional, reduced secondary current that allows electrical instruments to measure larger primary currents safely and conveniently. The Lovato DM2TMA0250 converts a 250 A primary current to a standard 5 A secondary signal, allowing it to interface with compatible energy meters, ammeters and power-monitoring equipment.
The split-core arrangement is especially valuable when adding metering or monitoring to an existing electrical installation. The core can be opened and positioned around the conductor without removing the conductor from the circuit, reducing installation work and making the DM2TMA0250 a practical choice for retrofit energy-management and industrial monitoring projects.
