Lumel LCTB 62/40 Current Transformer 600/5A Class 0.5

The Lumel LCTB 62/40 current transformer is a high-precision instrument engineered for accurate electrical current measurement within industrial environments. Designed for integration into low-voltage distribution networks, this device facilitates the conversion of high primary currents into manageable secondary signals suitable for energy monitoring, metering, and protection systems. Its robust design ensures consistent performance and reliability in demanding electrical infrastructures.

Advantages

The primary benefit of this current transformer lies in its high accuracy class of 0.5, which guarantees precise data acquisition for energy management and billing applications. The busbar-mounted configuration allows for straightforward installation in existing switchgear panels, minimizing downtime during setup. Furthermore, the durable construction provides long-term stability, ensuring that the device maintains its measurement integrity even under continuous operational loads in industrial settings.

Suitable for

• Energy monitoring and management systems
• Low-voltage electrical distribution networks
• Industrial metering and sub-metering applications
• Protection relay circuits

This device is not suitable for high-voltage applications exceeding its rated insulation levels. It is also not intended for use in environments where the primary current significantly exceeds the rated 600A capacity, as this may lead to saturation and inaccurate readings.

Key specifications

• Transformation ratio: 600/5A
• Accuracy class: 0.5
• Mounting type: Busbar
• Aperture size: 62/40 mm

To use the Lumel LCTB 62/40, ensure the primary conductor is passed through the aperture of the transformer, ensuring proper alignment with the busbar. Connect the secondary terminals to the measuring or protection equipment using appropriately sized wiring. Always verify that the secondary circuit is never left open while the primary circuit is energized to prevent dangerous voltage spikes.

What to consider before purchase

• Verify that the busbar dimensions are compatible with the 62/40 mm aperture
• Ensure the primary current of your system matches the 600A rating
• Confirm that the accuracy requirements of your application align with class 0.5

For optimal performance and safety, ensure all connections are tightened to the manufacturer's specified torque and that the secondary circuit is properly grounded according to local electrical regulations.
