Why Choose the Lovato DM4TA2000 Split-Core Current Transformer?
The Lovato DM4TA2000 is a high-capacity split-core current transformer designed for accurate current measurement in industrial switchboards, power distribution systems and energy monitoring installations. With a rated primary current of 2000 A and a standard 5 A secondary output, it converts high line currents into a safe and proportional signal for compatible meters, network analysers, ammeters and protection equipment.
Unlike a conventional solid-core transformer, the DM4TA2000 features an opening split-core construction that can be installed around an existing conductor or busbar without disconnecting the primary circuit. This makes it particularly suitable for retrofit projects, system upgrades and maintenance work where minimising installation disruption is important.
The transformer has a generous 80 × 160 mm internal opening for large busbars and conductor assemblies. It provides a rated burden of 15 VA at accuracy class 0.5 and 20 VA at accuracy class 1, supporting dependable metering and electrical monitoring in demanding high-current applications.
Key Advantages
- High-capacity 2000/5 A current transformation ratio.
- Split-core construction allows installation around existing conductors.
- Large 80 × 160 mm internal opening for substantial busbar systems.
- Reduces installation time and avoids disconnecting the primary conductor.
- Class 0.5 and class 1 accuracy performance for metering and monitoring.
- Suitable for energy meters, network analysers, ammeters and protection relays.
Key Features
- Lovato Electric DM series current transformer.
- Split-core design for retrofit installation.
- 2000 A rated primary current.
- 5 A rated secondary current.
- 50/60 Hz operating frequency.
- 15 VA burden at accuracy class 0.5.
- 20 VA burden at accuracy class 1.
- 120% rated primary-current overload withstand.
- 80 × 160 mm conductor opening.
- Screw terminals and screw fixing for secure installation.
Flexible High-Current Measurement for Existing Installations
Current transformers reduce high primary currents to a standard secondary value that can be safely measured by compatible electrical instruments. The Lovato DM4TA2000 converts a primary current of up to 2000 A into a proportional 5 A signal, enabling accurate load and energy monitoring without carrying the full current through the measuring device.
Its split-core construction allows the transformer to be opened and fitted around an installed conductor or busbar. This provides a practical solution for retrofitting energy monitoring equipment, expanding an existing metering system or replacing a transformer where dismantling the primary circuit would be difficult or disruptive.
Typical Applications
- Retrofit energy metering installations.
- High-current industrial switchboards.
- Electrical distribution and busbar systems.
- Power quality and energy monitoring equipment.
- Digital multimeters and network analysers.
- Current indication and monitoring systems.
- Protection relay installations.
- Commercial buildings and manufacturing facilities.
