Current transformer 100/5A Ø22, class 0.5 TI-100-5

Current transformer for precise measurements

This current transformer, with a ratio of 100/5A, is a reliable tool for measuring current in electrical circuits. Designed for both industrial and building installations, it provides accurate and safe load monitoring. Accuracy class 0.5 guarantees high measurement precision, which is crucial in control and protection systems.

Construction and application

The through-type current transformer with a closed core is ideal for use with various measuring and control devices. It serves to convert large currents into values safe for meters, counters and relays. This enables effective energy consumption monitoring and protection of installations against overloads and short circuits. The transformer is used in electrical switchboards, control cabinets and energy monitoring systems.
