Current transformer CT 300/5 A diameter 32 / 40.5x10.5 412124

(Remove "High quality" and "Stainless steel" - these are not in the original text) Current transformer for precise measurement

This current transformer from Legrand, model CT 300/5 A, is a reliable tool for measuring current in electrical installations. Designed for both residential and industrial applications, it provides accurate data essential for monitoring energy consumption and ensuring safety. The transformer's design allows for mounting on a rail or directly on the wire, making it easy to integrate with existing infrastructure.

Construction and application

The CT 300/5 A current transformer is used to convert a high primary current (up to 300 A) to a lower, safe secondary current (5 A), which can be measured by standard ammeters, electricity meters or network analyzers. This allows for safe and accurate measurement of the load in electrical circuits. It is certified, which confirms its compliance with applicable metrological standards and regulations. It is designed to work with ammeters, energy meters and multi-meters.

Key features and benefits

• Measurement accuracy: Accuracy class 0.5 guarantees precise readings, which is crucial for correct energy billing and optimizing installation performance.
• Safety: Galvanic isolation between the primary and secondary circuits provides protection against electric shock. Touch protection further increases safety.
• Universal mounting: The possibility of mounting on a 32 mm diameter wire or on a 40.5 x 10.5 mm rail provides flexibility during installation in various conditions.
• High overload resistance: Overcurrent factor FS 5 means the transformer can temporarily withstand a much higher current than its rated current without damage - useful for starting motors or other high-power devices.
• Solid connections: Secondary circuit connection using screw connections ensures a reliable and durable electrical connection.
• Compliance with standards: The transformer's certification confirms its compliance with applicable metrological regulations, which is important for billing and control purposes.
• Rated power of the secondary side: 5 VA allows you to connect a wide range of measuring devices without fear of overloading the transformer.
