Why Choose the Lovato DM2TA0250 Split-Core Current Transformer?
The Lovato DM2TA0250 is a robust split-core current transformer designed for reliable current measurement in industrial switchboards, electrical distribution panels and energy-monitoring systems. Featuring a 250/5 A transformation ratio, it converts a primary current of up to 250 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 enables the transformer to be opened and installed around an existing conductor or busbar without disconnecting the primary circuit. This makes the DM2TA0250 particularly suitable for retrofit metering projects, energy-management upgrades and operational installations where reducing electrical downtime is important.
The transformer features a large 80 × 80 mm internal opening suitable for substantial cables and busbars used within industrial power-distribution equipment. Operating at 50/60 Hz, it provides a burden of 1 VA at accuracy class 0.5 and 2 VA at accuracy class 1, supporting dependable measurement across a wide range of electrical monitoring applications.

Reliable Current Measurement for Retrofit Installations
Current transformers provide a safe method of measuring high electrical currents by converting the primary current into a proportional secondary signal suitable for compatible instrumentation. The Lovato DM2TA0250 converts a primary current of up to 250 A into a standard 5 A secondary output, enabling energy meters and monitoring equipment to measure electrical loads without direct connection to the high-current circuit.
The split-core design is particularly valuable when adding metering equipment to an existing electrical installation. The transformer can be opened, positioned around the cable or busbar and securely closed without removing the primary conductor. This helps reduce installation labour, system modification and operational disruption.
Typical Applications
- Industrial switchboards and power-distribution panels.
- Energy meters and multifunction measuring instruments.
- Power analysers and electrical monitoring systems.
- Building and facility energy-management systems.
- Electrical load and demand monitoring.
- Industrial machinery and automation panels.
- Commercial power-distribution installations.
- Retrofit metering and energy-efficiency projects.
