Why Choose the Lovato DM1TA0400 Split-Core Current Transformer?
The Lovato DM1TA0400 is a high-performance split-core current transformer (CT) designed for accurate current measurement in industrial and commercial electrical systems. Featuring a 400/5 A transformation ratio, it converts high primary currents into a standard 5 A secondary output suitable for multifunction power meters, energy analysers and protection devices.
Its split-core design allows installation around an existing cable or busbar without disconnecting the primary conductor, making it ideal for retrofit energy monitoring projects, electrical upgrades and maintenance work where downtime must be minimised.
With a large 52 × 80 mm internal window, Class 0.5 accuracy at 1.5 VA and Class 1 accuracy at 3 VA, the DM1TA0400 delivers dependable performance for switchboards, distribution systems and industrial automation installations. It is manufactured to IEC standards and offers robust long-term reliability.
