Why Choose the Lovato DM4T1000 Current Transformer?
The Lovato DM4T1000 is a robust solid-core current transformer designed for accurate AC current measurement in industrial electrical distribution, energy monitoring and metering systems. Part of the Lovato DM4T current transformer range, it provides a 1000/5 A transformation ratio, converting a rated primary current of 1000 A into a standard 5 A secondary current for compatible measuring instruments.
Designed for high-current installations, the DM4T1000 features a large Ø86 mm cable aperture and can also accommodate 100 × 30 mm, 80 × 50 mm and 70 × 60 mm busbars. This versatile conductor capacity makes it particularly suitable for main switchboards, industrial distribution panels and power-monitoring systems using substantial cables or busbar arrangements.
Operating at 50–60 Hz, the DM4T1000 provides class 0.5 accuracy at 10 VA and class 1 accuracy at 20 VA. It also offers a 720 V rated insulation voltage, 120% continuous primary-current overload withstand, screw terminals and flexible DIN rail or screw mounting for dependable integration into electrical installations.

Reliable High-Current Measurement for Electrical Monitoring
Current transformers reduce large primary currents to a proportional secondary current that can be measured safely by compatible electrical instrumentation. The Lovato DM4T1000 converts a 1000 A primary current into a standard 5 A secondary current, allowing energy meters, ammeters and power analysers to monitor high electrical loads without carrying the full primary current through the measuring instrument.
The large Ø86 mm cable aperture and compatibility with multiple busbar dimensions make the DM4T1000 particularly useful in high-current distribution systems. Its solid-core construction, class 0.5 measurement capability and flexible mounting arrangement provide a dependable solution for industrial switchboards, energy-management systems and electrical power-monitoring installations.
Typical Applications
- High-current industrial electrical distribution systems.
- Main switchboards and distribution panels.
- Commercial and industrial energy metering.
- Busbar current measurement installations.
- Industrial power and load monitoring.
- Power analysers and multifunction electrical meters.
- Building and plant energy-management systems.
