The Lovato DM4T3000 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 3000 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 DM4T3000 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 or busbar can be passed through the transformer during installation.
The DM4T3000 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 45 VA at accuracy class 0.5 and 45 VA at accuracy class 1, supporting reliable measurement in demanding high-current applications.
Current transformers allow high electrical currents to be measured safely by reducing the primary current to a standard secondary value. The Lovato DM4T3000 converts a primary current of up to 3000 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 DM4T3000 can support energy management, load monitoring, electrical protection and preventative maintenance across industrial and commercial installations.
