Why Choose the Lovato DM0T0100 Current Transformer?
The Lovato DM0T0100 is a compact and dependable solid-core current transformer designed for accurate current measurement in industrial and commercial electrical systems. Featuring a 100/5 A transformation ratio, it converts a primary current of 100 A into a standard 5 A secondary signal for compatible meters, energy analysers and monitoring equipment.
As part of the established Lovato DM current transformer range, the DM0T0100 provides Class 1 measurement accuracy with a rated burden of 1.5 VA. Its solid-core construction delivers a secure magnetic circuit, while the 22 mm circular cable aperture makes it suitable for installation around appropriately sized insulated conductors during switchboard assembly.
Designed for operation on 50/60 Hz electrical systems, the DM0T0100 offers a rated insulation voltage of 720 V and continuous overload capability up to 120% of its rated primary current. It is an effective choice for power distribution, energy monitoring and industrial automation applications where reliable current conversion is essential.

Reliable Current Measurement for Electrical Systems
The Lovato DM0T0100 produces a proportional secondary current that allows connected measuring equipment to monitor a 100 A circuit without carrying the full primary load. This provides electrical isolation between the measured conductor and the connected instrumentation while enabling accurate current measurement throughout the installation.
Its standard 5 A output is compatible with a wide range of multifunction meters, power analysers and energy management devices. The solid-core construction makes it particularly suitable for new control panels and switchboards where the primary conductor can be passed through the transformer during assembly.
Typical Applications
- Electrical distribution panels.
- Industrial switchboards.
- Multifunction power meters.
- Energy monitoring systems.
- Power quality analysers.
- Motor control centres.
- Building management systems.

Frequently Asked Questions
What is the Lovato DM0T0100 used for?
The DM0T0100 converts a 100 A primary current into a standard 5 A secondary signal for compatible electrical meters, analysers and monitoring equipment.
What transformation ratio does the DM0T0100 provide?
The current transformer has a 100/5 A transformation ratio.
What is the cable aperture of the DM0T0100?
The transformer has a 22 mm diameter circular aperture through which the monitored conductor is passed.
What is the rated burden of this current transformer?
The Lovato DM0T0100 has a rated burden of 1.5 VA at Class 1 accuracy.
Can the DM0T0100 be installed around an existing connected cable?
No. The DM0T0100 has a solid core, so the conductor must be disconnected and passed through the aperture during installation. A split-core transformer is normally required for installation around an existing connected cable.
