Current transformer CT 200/5 A diameter 21 / 16x12.5 412106

Current transformer – precise measurement and installation protection

This current transformer is a key element in measurement and protection systems. It enables safe and accurate current measurement in electrical circuits, while simultaneously protecting against the effects of overloads. It is indispensable both in industrial, commercial and residential installations where precision and reliability are required.

Construction and application

The CT 200/5 A current transformer is designed to work with circuits with a primary current of up to 200 A, converting it into a safe secondary signal of 5 A. The aperture diameter of 21 mm allows for convenient cable routing, and the solid construction ensures durability and resistance to damage. Thanks to the accuracy class of 0.5, it guarantees precise measurements, which is important in applications requiring high reading accuracy. The use of current transformers allows for monitoring network load, detecting irregularities and responding quickly in the event of a failure.

Key features and benefits

• Safety: Equipped with touch protection, it minimizes the risk of electric shock during operation and maintenance.
• Precision: Accuracy class 0.5 ensures reliable measurement results, which is crucial for the correct operation of monitoring and control systems.
• Durability: Solid construction guarantees long-lasting and trouble-free operation even in difficult operating conditions.
• Easy installation: Screw connection of the secondary circuit facilitates and speeds up installation, minimizing system downtime.
• Calibrated: Ready to use immediately after connection - no additional calibration is required saves time and costs.
• FS 5 burden rating: Ensures stable operation during short-term overloads, protecting the device from damage.
• Rated apparent power 4 VA: Suitable for most standard measuring and protection devices.
