Lovato Electric DM2T0100 Current Transformer 100/5A 1VA Class 1 for Cable and Busbar

The Lovato Electric DM2T0100 is a precision-engineered current transformer designed for accurate electrical measurement in industrial environments. With a transformation ratio of 100/5A and a 1VA output, this device is specifically calibrated for Class 1 accuracy, making it an essential component for monitoring power consumption and ensuring the efficiency of electrical distribution systems. Its robust construction allows for versatile installation on both cables and busbars, providing a reliable solution for control panels and energy management applications.

Advantages

This current transformer offers high measurement precision, ensuring that energy data remains accurate for billing or monitoring purposes. The compact design facilitates easy integration into crowded control panels, while the flexible mounting options allow it to be used with various cable diameters and busbar dimensions. Its durable build quality ensures long-term operational stability in demanding industrial settings, reducing the need for frequent maintenance or replacement.

Suitable for

• Industrial power distribution systems
• Energy management and monitoring circuits
• Control panels and switchgear
• Current measurement for protection relays

This device may not be suitable for high-voltage applications exceeding its rated insulation levels or for environments where the primary current significantly exceeds the 100A rating, as this could lead to measurement inaccuracies or damage to the transformer. It is also not intended for use in circuits requiring higher accuracy classes than Class 1.

Key specifications

• Transformation ratio: 100/5A
• Accuracy class: 1
• Rated output: 1VA
• Maximum cable diameter: 23mm
• Busbar dimensions: 10x30mm or 15x20mm

To use the Lovato Electric DM2T0100, ensure the primary conductor is passed through the aperture of the transformer, ensuring correct orientation according to the markings on the device. Connect the secondary terminals to the measuring instrument or protection relay using appropriately sized wiring. Verify that all connections are tight and that the secondary circuit is never left open while the primary circuit is energized to prevent dangerous voltage buildup.

What to consider before purchase

• Verify the primary current rating matches your specific application requirements
• Check that the physical dimensions of your cables or busbars fit within the specified aperture limits
• Ensure the secondary burden of your measuring device does not exceed the 1VA output rating

For optimal performance and safety, always ensure that the secondary circuit is connected to a load before energizing the primary conductor. Regular inspection of the connections is recommended to maintain measurement accuracy over time.
