Schneider Electric METSECT5CC015 Current Transformer 150/5A 3VA Class 0.5 FS5 for 21mm Cable

The Schneider Electric METSECT5CC015 is a high-precision current transformer engineered for accurate electrical measurement and monitoring within power distribution systems. This device is designed to convert high primary currents into a manageable 5A secondary signal, facilitating precise data collection for energy management and industrial automation. With a compact design suitable for cables up to 21mm in diameter, it integrates seamlessly into existing electrical panels and infrastructure.

Advantages

This current transformer offers exceptional reliability and measurement accuracy, meeting the 0.5 accuracy class standards required for professional energy monitoring. Its robust construction ensures consistent performance in demanding industrial environments, while the FS5 safety factor provides essential protection for downstream measuring equipment during overcurrent conditions. The unit is designed for easy installation, allowing for efficient deployment in both new projects and system upgrades.

Suitable for

• Energy monitoring and management systems
• Industrial power distribution panels
• Commercial building electrical sub-metering
• Current signal conversion for protection relays

This device may not be suitable for applications requiring high-voltage insulation beyond standard low-voltage distribution levels or for environments where cable diameters exceed 21mm. It is also not intended for direct connection to high-power loads without appropriate secondary measuring instruments.

Key specifications

• Transformation ratio: 150/5A
• Accuracy class: 0.5
• Power output: 3VA
• Safety factor: FS5
• Maximum cable diameter: 21mm

To use this current transformer, ensure the primary conductor is passed through the aperture of the device, ensuring the cable is centered for optimal accuracy. Connect the secondary terminals to your measuring device or energy meter using appropriate wiring, ensuring that all connections are secure and follow the polarity markings. Always verify that the secondary circuit is never left open while the primary circuit is energized to prevent dangerous voltage build-up.

What to consider before purchase

• Verify that the primary current of your system matches the 150A rating
• Check that the cable diameter does not exceed 21mm
• Ensure the secondary measuring device is compatible with a 5A input
• Confirm the required accuracy class for your specific application

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