Schneider Electric METSECT5CC004 Current Transformer 40/5A 1VA Class 3 FS5 for 21mm Cable

The Schneider Electric METSECT5CC004 is a precision-engineered current transformer designed to facilitate accurate electrical current measurement in various industrial and commercial applications. This device converts high primary currents into manageable secondary currents, allowing for reliable monitoring and integration with energy management systems. Built with robust materials, it ensures consistent performance and durability in demanding electrical environments.

Advantages

This current transformer offers exceptional reliability for power monitoring tasks, ensuring that electrical data remains precise and actionable. Its compact design allows for easy installation on cables up to 21mm in diameter, making it a versatile choice for space-constrained electrical cabinets. The inclusion of an FS5 safety factor provides enhanced protection for connected measuring instruments during overcurrent conditions, while the high-quality construction guarantees long-term operational stability.

Suitable for

• Industrial power monitoring systems
• Energy management and sub-metering applications
• Electrical distribution panels
• Current sensing for control and automation equipment

When it may not be suitable

This device is not intended for use in high-voltage power transmission lines or applications requiring high-precision billing accuracy, as it operates within accuracy class 3. It is also unsuitable for cables exceeding 21mm in diameter or for environments where the power burden exceeds the 1VA rating.

Key specifications

• Transformation ratio: 40/5A
• Power rating: 1VA
• Accuracy class: 3
• Safety factor: FS5
• Maximum cable diameter: 21mm

How to use

Installation should be performed by a qualified electrician in accordance with local electrical safety standards. The transformer is mounted directly onto the primary conductor by passing the cable through the central aperture. Ensure the cable is centered and securely fastened to prevent movement. Connect the secondary terminals to the measuring device or energy meter using appropriate wiring, ensuring that the polarity is correctly observed to maintain measurement accuracy.

What to consider before purchase

• Verify that the primary current does not exceed the 40A rating.
• Ensure the cable diameter is 21mm or less.
• Confirm that the 1VA power burden is sufficient for your specific measuring instrument.
• Check that accuracy class 3 meets your project requirements.

Usage recommendations

Always ensure that the secondary circuit is connected to a load or short-circuited before energizing the primary conductor to prevent dangerous voltage build-up.
