Why Choose the Lovato DM1TA0800 Split-Core Current Transformer?
The Lovato DM1TA0800 is a high-quality split-core current transformer engineered for accurate current measurement in industrial power distribution, energy management and electrical monitoring applications. Designed with an 800/5 A transformation ratio, it provides a standard 5 A secondary output for connection to energy meters, multifunction power analysers, ammeters and protection devices.
Its practical split-core construction allows the transformer to be installed around existing conductors or busbars without disconnecting the primary circuit. This significantly reduces installation time and system downtime, making it an ideal solution for retrofit energy-monitoring projects as well as new switchboard installations.
Featuring a generous 52 × 80 mm internal opening, the DM1TA0800 accommodates large conductors commonly found in commercial and industrial electrical panels. Designed for 50/60 Hz operation, it delivers measurement burdens of 3 VA at accuracy class 0.5 and 7.5 VA at accuracy class 1, ensuring dependable performance across a wide range of monitoring applications.
