Why Choose the Lovato DM2TA0400 Split-Core Current Transformer?
The Lovato DM2TA0400 is a dependable split-core current transformer designed for accurate current measurement in industrial switchboards, electrical distribution panels and energy-monitoring systems. Featuring a 400/5 A transformation ratio, it converts a primary current of up to 400 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 DM2TA0400 particularly suitable for retrofit metering projects, power-monitoring upgrades and operational installations where reducing downtime and avoiding extensive electrical modifications are 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 1.5 VA at accuracy class 0.5 and 3 VA at accuracy class 1, supporting dependable current 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 DM2TA0400 converts a primary current of up to 400 A into a standard 5 A secondary output, enabling meters and monitoring equipment to measure electrical loads without being connected directly 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, electrical system modification and operational disruption.
