Why Choose the Lovato DM4T2500 Current Transformer?
The Lovato DM4T2500 is a high-capacity solid-core current transformer designed for accurate current measurement in industrial switchboards, electrical distribution panels and energy monitoring systems. With a rated primary current of 2500 A and a standard 5 A secondary output, it converts high line currents into a safe and proportional signal for compatible meters, network analysers and protection equipment.
As part of the established Lovato Electric DM current transformer range, the DM4T2500 provides dependable measurement performance for panel builders, electrical contractors and industrial engineers. Its solid-core construction creates a stable magnetic circuit, making it particularly suitable for new electrical assemblies where the conductor can be passed through the transformer during installation.
The DM4T2500 accommodates cables up to 86 mm in diameter and can be installed around 100 × 30 mm, 80 × 50 mm or 70 × 60 mm busbars. It provides a rated burden of 35 VA at accuracy class 0.5 and 45 VA at accuracy class 1, supporting reliable current measurement in demanding high-load applications.

Reliable High-Current Measurement for Electrical Systems
Current transformers allow high electrical currents to be measured safely by reducing the primary current to a standard secondary value. The Lovato DM4T2500 converts a primary current of up to 2500 A into a proportional 5 A signal, allowing compatible measuring instruments to monitor the circuit without carrying the full load current.
Its large conductor aperture, high rated burden and solid-core design make it suitable for high-current power-distribution systems. When connected to compatible instrumentation, the DM4T2500 can support energy management, load monitoring, electrical protection and preventative maintenance across industrial and commercial installations.
Typical Applications
- High-current industrial switchboards.
- Low-voltage electrical distribution panels.
- Energy metering and power management systems.
- Digital multimeters and network analysers.
- Current indication and monitoring equipment.
- Protection relay installations.
- Manufacturing and process-control facilities.
- Commercial and infrastructure power-distribution systems.
