Why Choose the Lovato DM33T1200 Current Transformer?
The Lovato DM33T1200 is a reliable solid-core current transformer designed for electrical current measurement in switchboards, power distribution systems and industrial installations. With a 1200 A primary current and 5 A secondary output, it converts high circuit currents into a standardised signal suitable for compatible meters, analysers and monitoring equipment.
Designed for installation around conductors without requiring the measured current to pass directly through instrument terminals, the DM33T1200 features a 44 mm diameter opening and can also accommodate suitable busbars. Its solid-core construction, screw secondary terminals and flexible mounting options make it well suited to permanent electrical installations where dependable current measurement is required.
The DM33T1200 provides class 0.5 accuracy with a 5 VA burden and class 1 accuracy with a 15 VA burden. It operates at 50–60 Hz, has a rated insulation voltage of 720 V and is suitable for DIN rail or screw fixing in industrial electrical assemblies.

Reliable Current Measurement for Electrical Systems
Current transformers reduce high primary currents to a proportional secondary current that can be safely used by compatible measuring instruments. With its 1200/5 A ratio, the Lovato DM33T1200 enables meters and monitoring devices to measure substantial load currents without carrying the full primary circuit current through the measuring equipment.
The solid-core design is particularly suitable for new installations where the conductor can be routed through the transformer during assembly. Its combination of class 0.5 measurement accuracy, standard 5 A secondary output and flexible mounting makes the DM33T1200 a practical choice for industrial switchboards, energy monitoring and electrical distribution applications.
Typical Applications
- Industrial electrical switchboards and control panels.
- Power distribution and low-voltage electrical systems.
- Current measurement and electrical metering.
- Energy monitoring and power analysis systems.
- Industrial machinery and plant electrical installations.
- Busbar and high-current cable monitoring.
