Its robust construction and compact design allow for seamless integration into industrial and commercial electrical panels, ensuring reliable data acquisition for monitoring systems.

Advantages

This current transformer offers exceptional measurement accuracy, which is critical for maintaining precise energy consumption records and optimizing power usage. The versatile mounting options allow it to be installed on either cables or busbars, providing flexibility for various electrical configurations. Its compact physical footprint is specifically optimized for space-constrained environments, such as standard DIN rail electrical panels, while the IP20 protection rating ensures that the internal components are shielded from solid objects during operation.

Suitable for

• Energy monitoring and power management systems
• Sub-metering in commercial and industrial buildings
• Current measurement in electrical distribution panels
• Integration with power meters and data loggers

This device may not be suitable for outdoor environments or areas exposed to moisture, dust, or corrosive substances, as it carries an IP20 protection rating. It is also not intended for high-voltage transmission lines or applications requiring transformation ratios outside of the specified 400/5A range.

Key specifications

• Transformation ratio: 400/5A
• Mounting type: Cable and busbar
• Protection rating: IP20
• Width: 56 mm
• Depth: 43 mm
• Height: 80 mm

To use the Schneider Electric current transformer, ensure the power supply to the circuit is disconnected before installation. Secure the device onto the designated cable or busbar according to the mechanical specifications. Connect the secondary terminals to your measuring instrument or power meter using appropriate wiring. Once installed, verify that the connections are tight and that the transformer is properly oriented to ensure accurate current readings before restoring power to the system.

What to consider before purchase

• Verify that the 400/5A ratio matches your specific monitoring requirements
• Ensure the physical dimensions are compatible with your existing panel space
• Confirm that the installation environment meets the IP20 protection standards

Usage recommendations: Always consult with a qualified electrician for installation to ensure compliance with local electrical codes and safety standards. Regularly inspect the connections to maintain measurement accuracy and system integrity.
