Why Choose the Lovato DM3T0800 Solid-Core Current Transformer?
The Lovato DM3T0800 is a robust solid-core current transformer designed for accurate current measurement in industrial switchboards, electrical distribution panels and energy-monitoring systems. Featuring an 800/5 A transformation ratio, it converts a primary current of up to 800 A into a standard 5 A secondary output for connection to compatible energy meters, ammeters, multifunction measuring instruments 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 DM3T0800 accommodates round cables up to 30 mm in diameter and rectangular busbars measuring 40 × 10 mm, 30 × 20 mm or 25 × 25 mm, offering flexibility across a range of switchgear and control-panel configurations.
Operating at 50–60 Hz, the transformer provides a burden of 5 VA at accuracy class 0.5 and 10 VA at accuracy class 1. Faston secondary terminals, DIN rail or screw mounting and an IP30 protection rating help simplify installation while supporting dependable long-term current measurement.

Accurate 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 DM3T0800 converts a primary current of up to 800 A into a standard 5 A secondary signal, allowing meters and monitoring devices to measure electrical loads without being connected directly to the high-current circuit.
The solid-core construction is particularly suitable for new switchboard and control-panel assemblies. During installation, the cable or busbar is passed through the transformer opening before the primary circuit is connected. This creates a secure arrangement for continuous energy measurement, electrical load monitoring and power-system analysis.
Typical Applications
- Industrial switchboards and power-distribution panels.
- Energy meters and multifunction measuring instruments.
- Power analysers and electrical monitoring systems.
- Building energy-management systems.
- Industrial machinery and automation panels.
- Electrical load and maximum-demand monitoring.
- Commercial power-distribution installations.
- New panel-building and switchgear projects.
