Current transformer 200/5A Ø22, class 0.5 TI-200-5

Current transformer – precise measurement and installation protection

This current transformer, with a transformation ratio of 200/5A, is a reliable tool for measuring current in electrical circuits. Designed for both industrial and building installations, it provides accurate readings and safe system operation. Accuracy class 0.5 guarantees high measurement precision, which is crucial for effective energy consumption monitoring and proper operation of protective devices.

The transformer is designed for mounting on a 22 mm diameter conductor or on a busbar. Its closed-core design ensures stability and resistance to interference. Therefore, regardless of the operating conditions, the transformer delivers reliable measurement data.

Construction and application

A through-type current transformer is an essential element in measurement and protection systems. It serves to convert large primary currents (up to 200A) into smaller secondary currents (5A), which are safe and easy to read by meters, counters and protective relays. Using a transformer allows for:

• Current measurement: Accurate measurement of current intensity in the circuit.

• Overload protection: Cooperation with automatic circuit breakers to protect the installation from damage caused by overload.

• Short-circuit protection: Fast response to a short circuit, minimizing the risk of fire and equipment damage.

• Energy consumption monitoring: Precise tracking of power consumption to optimize energy costs.

Technical characteristics and benefits

The transformer is characterized by a solid construction and high quality of workmanship. The rated secondary apparent power is 5 VA, which ensures stable operation even under heavy loads. The FS 5 overload coefficient means that the transformer can temporarily withstand currents significantly exceeding the rated value without damage. The connection of the secondary circuit is made using a screw connection, which ensures a secure and durable electrical connection.

• High accuracy: Accuracy class 0.5 guarantees precise current measurements.

• Wide range of applications: Suitable for industrial, building installations and energy monitoring systems.

• Safety: Provides effective protection against overload and short circuit.

• Durability: Solid construction with high-quality materials guarantees long-term operation.

• Easy installation: Designed for mounting on a conductor or busbar – quick and easy mounting on a panel or busbar thanks to 32x21 mm holes for a 22mm diameter conductor.

• Compliance with standards: Meets the requirements of IEC 60044-1, which confirms its safety and reliability.
