Current transformer 30/5a 22, class 1 TI-30-5

Current transformer – precise measurement and installation protection

The TI-30-5 current transformer is a reliable device used to measure current in electrical circuits and provide protection against the effects of overloads and short circuits. The closed-core design and accuracy class 1 guarantee precise readings, which is crucial in both industrial applications and building installations. The conductor diameter of 22 mm allows mounting on cables of various thicknesses.

Construction and application

The TI-30-5 through-type transformer is designed for mounting on busbars or distribution boards. Its versatility allows it to be used in various electrical installation configurations. The rated primary current of 30A, combined with the secondary current of 5A, ensures optimal adaptation to the needs of a specific circuit. The device is used in measurement systems, energy consumption monitoring, as well as in overload and short-circuit protection systems. Using a transformer allows for safe and efficient operation of the electrical installation.
