Lovato DM1TA1000 split-core current transformer with a 1000/5 A transformation ratio, 52 x 80 mm opening, 5 VA class 0.5 burden and 10 VA class 1 burden for industrial electrical metering.
£133.60
The Lovato DM1TA1000 is a dependable split-core current transformer designed for measuring high electrical currents in industrial power distribution, energy management and electrical monitoring systems. With a 1000/5 A transformation ratio, it converts a primary current of up to 1000 A into a standard 5 A secondary signal for compatible ammeters, energy meters, multifunction measuring instruments and monitoring equipment.
Its split-core construction enables the transformer to be opened and installed around an existing cable or busbar without disconnecting the primary conductor. This makes the DM1TA1000 particularly suitable for retrofit installations, electrical system upgrades and energy-monitoring projects where minimising disruption and installation time is important.
Featuring a large 52 × 80 mm internal opening, the transformer can accommodate substantial conductors and rectangular busbars used in industrial switchboards and distribution panels. It provides a rated burden of 5 VA at accuracy class 0.5 and 10 VA at accuracy class 1, supporting reliable current measurement across a wide range of commercial and industrial applications.
Current transformers allow high electrical currents to be measured safely by converting the primary current into a proportional secondary signal. The Lovato DM1TA1000 reduces a primary current of up to 1000 A to a standard 5 A output, allowing compatible measuring instruments to monitor electrical loads without being connected directly to the high-current circuit.
The split-core format is especially useful when adding metering equipment to an existing installation. The transformer can be opened, positioned around the conductor and secured without removing the cable or busbar. This supports efficient installation in operational switchboards while helping reduce downtime and modification work.

The DM1TA1000 is used to measure high currents in industrial and commercial electrical systems. It converts a primary current of up to 1000 A into a standard 5 A secondary signal for compatible metering and monitoring equipment.
The transformer has a 1000/5 A transformation ratio, meaning that a nominal primary current of 1000 A corresponds to a 5 A secondary output.
Yes. Its split-core construction allows the transformer to be opened and installed around an existing cable or busbar without disconnecting the primary conductor.
The transformer has a 52 × 80 mm internal opening, making it suitable for large cables and rectangular busbars within those dimensions.
The DM1TA1000 provides a burden of 5 VA at accuracy class 0.5 and 10 VA at accuracy class 1, depending on the connected secondary circuit and measuring equipment.
Lovato Electric current transformers are used by electrical engineers, panel builders and energy-management professionals to provide reliable current measurement, practical installation and dependable integration with modern metering systems.
