Lovato DM2T0100 solid-core current transformer with a 100/5 A transformation ratio, 23 mm cable opening, class 1 accuracy and 1 VA burden for electrical metering and monitoring.
£18.71
The Lovato DM2T0100 is a reliable solid-core current transformer designed for accurate current measurement in industrial switchboards, distribution panels and energy-monitoring systems. Featuring a 100/5 A transformation ratio, it converts a primary current of up to 100 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 assembly. The DM2T0100 accommodates round cables up to 23 mm in diameter and supports several common rectangular busbar sizes, offering installation flexibility within industrial control panels and low-voltage distribution equipment.
Operating at 50/60 Hz, the DM2T0100 provides a rated burden of 1 VA at accuracy class 1. Its compact housing, screw-terminal secondary connections and snap-mounting capability help simplify installation while providing dependable current measurement for monitoring electrical loads and energy consumption.
Current transformers provide a safe method of monitoring high electrical currents by producing a proportional lower-current output for compatible measuring instruments. The Lovato DM2T0100 converts a primary current of up to 100 A into a standard 5 A secondary signal, enabling accurate measurement without connecting monitoring equipment 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 installation suitable for continuous electrical load monitoring, energy measurement and power-management applications.

The DM2T0100 is used to measure electrical currents in switchboards, distribution panels and energy-monitoring systems. It converts a primary current of up to 100 A into a standard 5 A secondary output.
The current transformer has a 100/5 A transformation ratio, meaning that a nominal 100 A primary current corresponds to a 5 A secondary current.
The transformer can accommodate a round cable with a maximum diameter of approximately 23 mm.
The transformer is suitable for rectangular busbars measuring 30 × 10 mm, 25 × 12.5 mm or 20 × 15 mm.
No. The DM2T0100 has a solid-core construction, so the conductor must be disconnected or installed through the transformer opening during panel assembly. A split-core transformer is more suitable when the existing conductor cannot be disconnected.
Lovato Electric current transformers are used by panel builders, electrical contractors and industrial engineers to deliver reliable current measurement, straightforward integration and dependable performance in modern electrical distribution systems.
