Lovato DM1TA0800 split-core current transformer with an 800/5 A transformation ratio, 52 x 80 mm opening and 50/60 Hz operation for industrial electrical metering and energy monitoring.
£133.60
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.
Current transformers provide a safe and accurate method of measuring high electrical currents by converting the primary current into a proportional low-current output suitable for measuring instruments. The Lovato DM1TA0800 converts currents of up to 800 A into a standard 5 A secondary output, enabling accurate monitoring of electrical systems without direct connection to high-current conductors.
The split-core design allows installation around existing cables and busbars, making the transformer particularly suitable for upgrading existing switchboards and implementing energy-monitoring systems with minimal disruption to plant operation.
