Current transformer CT 700/5 A diameter 26 / 40.5x12.5 412119

Current transformer for precise measurements and protection

This CT 700/5 A current transformer is a reliable tool for measuring current in electrical installations. Designed for use in industry, commercial and residential construction, it provides accurate readings and effective circuit protection. Its design allows for safe and efficient load monitoring, which is crucial for optimizing energy consumption and minimizing the risk of failure.

Construction and application

The current transformer converts a high primary current (up to 700 A) into a low, safe secondary current (5 A) that can be measured by standard meters and monitoring systems. The aperture diameter of 26 mm allows mounting on cables of various thicknesses. Its compact dimensions (40.5x12.5 mm) allow installation even in limited space. It is designed to work with various measuring devices, such as energy meters, power quality analyzers or control systems.

• Measurement accuracy: Accuracy class 0.5 guarantees precise current readings, which is important for energy billing and load analysis.
• Safety: Touch protection ensures safety during operation and maintenance.
• Application in various installations: Ideal for energy consumption monitoring systems, protection against overloads and short circuits, and control of motors and other current consumers.
• Legalization: The transformer has legalization, which confirms its compliance with applicable standards and metrological regulations - important for settlements with the energy supplier.
• FS 5 burden factor: Allows momentary exceeding of the nominal current without damaging the device - useful when starting devices with high power consumption (e.g. motors).

Technical characteristics and installation

The transformer is characterized by a rated secondary apparent power of 8 VA and a power consumption of 8 W. The secondary circuit connection is realized by means of a screw connection, which ensures a reliable and durable electrical connection. Installation is simple and intuitive - the transformer is placed on the energized conductor. It is important to maintain the correct polarity when connecting the secondary circuit. Thanks to this, installers can quickly and efficiently integrate it with the existing electrical infrastructure. The design does not contain a copper busbar, which simplifies installation in some applications.
