The current transformer TZLU-125-1 is designed to protect circuits against short circuits in the cable, to transmit a signal about an emergency, etc. It is used to connect automatic machines, relay protection, control and alarm devices. It can be installed on a cable up to 125 mm. This cable passes through the transformer window. The current flowing through its cores creates magnetic fields, which are compensated for by the same bias angle.
As soon as the two cores come into contact, a magnetic field immediately arises, which leads to the appearance of voltage. This voltage is transferred to the relay circuit. The relay is triggered and the emergency is prevented. At the same time, a signal can be sent over the network. These products are installed in the switchgear indoors. They are manufactured in climatic version "U" (for temperate climates).
