Current transformer 200/5A Ø22, class 0.2s TI-200-5-02S

Current transformer for precise measurements and protection

A current transformer with a ratio of 200/5A is a key element in measurement and protection systems. It serves to safely and accurately convert large primary currents into smaller, easier-to-measure secondary values. This makes it possible to monitor the load, protect against overloads and short circuits, and power measuring and control devices. The closed-core design ensures high accuracy and measurement stability.

Construction and practical application

This current transformer, made with attention to detail, finds application in both industrial installations and commercial and residential buildings. Its versatility results from the possibility of mounting on distribution boards or busbars – both in vertical and horizontal positions. The current flowing through the wire placed in the transformer opening induces a secondary current proportional to the primary current. This allows for safe monitoring of the load without direct contact with high voltages. The use of current transformers is essential where precise measurements and reliable protection of the electrical installation are required.
