Why Choose the Lovato DM35T0800 Current Transformer?
The Lovato DM35T0800 is a solid-core current transformer designed for industrial electrical metering, power analysis and energy-monitoring applications. It provides an 800/5 A transformation ratio, converting a rated 800 A primary current into a standard 5 A secondary signal for compatible energy meters, multimeters and power analysers.
Designed for high-current conductors, the DM35T0800 accommodates cables up to Ø66 mm and busbars measuring 80 × 12.5 mm, 60 × 30 mm or 50 × 50 mm. It provides Class 0.5 accuracy at 10 VA and Class 1 accuracy at 15 VA, providing useful flexibility for industrial current and energy measurement.
The transformer operates at 50–60 Hz and features screw secondary terminals with DIN rail or screw fixing. Its 720 V rated insulation voltage, Class E dry-type insulation, IP30 protection and 120% continuous primary-current overload withstand support reliable service in industrial switchboards and power-distribution equipment.

Reliable & Accurate High-Current Measurement
The Lovato DM35T0800 allows compatible measuring equipment to monitor substantial AC loads without carrying the full primary current through the instrument. At rated current, the transformer converts 800 A on the primary conductor into a proportional 5 A secondary signal suitable for compatible current-input meters and power analysers.
Its large Ø66 mm opening and compatibility with several industrial busbar formats make the DM35T0800 particularly suitable for high-current switchboards and distribution systems. Class 0.5 measurement performance, industrial insulation characteristics and flexible mounting arrangements provide a dependable combination of accuracy and installation versatility.
Typical Applications
- Industrial electrical distribution boards.
- Energy meters and power analysers.
- Three-phase electrical metering systems.
- High-current industrial switchboards.
- Busbar current measurement.
- Building and facility energy-management systems.
- Electrical load and consumption monitoring.
