## Long description

The LOVATO Electric DM3T0400 is a high-precision current transformer engineered for accurate electrical measurement in industrial and commercial power distribution systems. With a transformation ratio of 400/5A and a power rating of 2.5VA, this device is designed to provide reliable data for energy management systems and protection relays. Its robust construction allows for versatile installation on both cables and busbars, making it an essential component for monitoring electrical currents in various infrastructure setups.
Advantages
This current transformer stands out due to its high accuracy class of 0.5, which ensures precise readings necessary for critical energy monitoring applications. The design is highly flexible, supporting mounting on either cables or busbars, which simplifies the integration process into existing electrical panels. Its compact and durable build ensures long-term operational stability, reducing the need for frequent maintenance while providing consistent performance in demanding electrical environments.
Suitable for
Energy management and monitoring systems
Protection relay applications
Industrial power distribution panels
Commercial electrical infrastructure
Current measurement in low-voltage switchgear
When it may not be suitable
This device is not intended for high-voltage applications or environments exceeding its specified power rating. It should not be used in systems where the primary current significantly deviates from the 400A rating, as this may compromise measurement accuracy or damage the unit.
Key specifications
Transformation ratio: 400/5A
Accuracy class: 0.5
Power rating: 2.5VA
Mounting type: Cable and busbar
How to use
Installation should be performed by qualified personnel in accordance with local electrical safety regulations. The transformer is mounted by passing the primary conductor through the aperture or securing it to the busbar using the provided mounting hardware. Ensure that the secondary terminals are connected to the measuring instrument or protection relay with appropriate wiring, maintaining correct polarity to ensure accurate readings. Always verify that the circuit is de-energized before beginning the installation process.
What to consider before purchase
Verify that the 400A primary current matches your system requirements
Ensure the 2.5VA burden capacity is sufficient for your connected measuring devices
Confirm the physical space available in your panel for cable or busbar mounting
Usage recommendations
For optimal performance and safety, ensure that all secondary connections are tightened securely and that the transformer is kept away from extreme heat sources. Regularly inspect the connections to prevent signal loss or measurement errors.
