Why Choose the Lovato DM2T0300 Solid-Core Current Transformer?
The Lovato DM2T0300 is a dependable solid-core current transformer designed for accurate current measurement in industrial switchboards, commercial distribution panels and energy-monitoring systems. Featuring a 300/5 A transformation ratio, it converts a primary current of up to 300 A into a standard 5 A secondary output for connection to compatible ammeters, energy meters, multifunction measuring instruments and power analysers.
Its solid-core construction provides a secure and durable measurement solution for new electrical installations where the primary conductor can be passed through the transformer during panel assembly. The DM2T0300 accommodates round cables up to 23 mm in diameter and supports several standard rectangular busbar sizes, providing installation flexibility within low-voltage switchgear and industrial control panels.
The transformer offers accuracy class 0.5 with a rated secondary apparent power of 1.5 VA, supporting dependable electrical metering and energy-management applications. Its compact housing, secure secondary connections and snap-mounting capability help simplify installation while providing reliable long-term current measurement.

Accurate Current Measurement for Electrical Distribution
Current transformers provide a safe method of monitoring high electrical currents by converting the primary current into a proportional lower-current output for compatible measuring instruments. The Lovato DM2T0300 converts a primary current of up to 300 A into a standard 5 A secondary signal, enabling accurate load measurement without connecting meters directly to the high-current circuit.
The solid-core format 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, 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 demand monitoring.
- Commercial power-distribution installations.
- New panel-building and switchgear projects.
