Why Choose the Lovato DM3TP0500 High-Accuracy Solid-Core Current Transformer?
The Lovato DM3TP0500 is a high-accuracy solid-core current transformer designed for dependable current measurement in industrial switchboards, electrical distribution panels and precision energy-monitoring systems. Featuring a 500/5 A transformation ratio, it converts a primary current of up to 500 A into a standard 5 A secondary output for connection to compatible energy meters, multifunction measuring instruments, ammeters and power analysers.
Its solid-core construction provides a secure and durable measuring solution for new electrical installations where the primary conductor can be routed through the transformer during panel assembly. The DM3TP0500 accommodates round cables up to 52 mm in diameter and rectangular busbars measuring 60 × 20 mm or 50 × 25 mm, making it suitable for substantial conductors used in industrial power-distribution equipment.
Designed for applications requiring enhanced measurement performance, the DM3TP0500 provides a rated burden of 3.75 VA at accuracy class 0.5S and 5 VA at accuracy class 0.5. Its robust construction, 50–60 Hz operating frequency and 720 V insulation rating support precise, stable current measurement in demanding commercial and industrial environments.

High-Accuracy Current Measurement for Electrical Panels
Current transformers provide a safe method of measuring high electrical currents by converting the primary current into a proportional lower-current output for compatible instrumentation. The Lovato DM3TP0500 converts a primary current of up to 500 A into a standard 5 A secondary signal, allowing meters and monitoring equipment to measure electrical loads without being connected directly to the high-current circuit.
The class 0.5S measurement capability makes this transformer especially suitable for applications where accurate readings are required across a wider operating range. Its solid-core construction is intended for new switchboard and control-panel assemblies, with the cable or busbar passed through the transformer before the primary circuit is connected.
Typical Applications
- Industrial switchboards and power-distribution panels.
- Revenue-grade and high-accuracy energy metering systems.
- Multifunction measuring instruments and power analysers.
- Building and facility energy-management systems.
- Electrical load and maximum-demand monitoring.
- Industrial machinery and automation panels.
- Commercial power-distribution installations.
- New panel-building and switchgear projects.
