AC/DC surge arrester 1+2 shorted TTV1+2-80-4 TRACON

Power limiters are otherwise known as lightning arresters. This is a product that ensures the safe mode of operation of the entire electrical system. Such an arrester has the task of protecting electrical apparatus from transient overvoltages and limiting the duration and value of the follow-up current. Short-circuiting of the installation can occur when lightning strikes an overhead line or as a result of connection or disconnection of an unloaded overhead line. This product is reusable. After a lightning strike, all you have to do is switch it again. It is very important that the connections are made with wires with a minimum cross-section of not less than 16 mm².

Such arresters are installed at the beginning of a cable or overhead installation, for example, at the main switchgear. In addition, such arresters provide protection against switching surges. Power limiters have a wide range of applications. They can also be installed at monitoring lines, photovoltaic installation and electronic devices used in industry. When selecting such a product, attention is paid to the waveform of the first surge current and the products that work with it, such as switching bushings, arrester stenciling and auxiliary contacts. Well-chosen products will form a complete equipment. With their help, you can avoid unnecessary failures.
