T1 35kA surge arrester cartridge 412286

Protection of electrical installations against overvoltage

A T1 surge arrester with a capacity of 35kA is a key element in protecting the electrical installation from the effects of lightning strikes and overvoltages. It provides first-level protection, grounding the energy of impulses caused by lightning strikes near the building or power lines. Its task is to limit the voltage to a safe level, protecting connected devices from damage.

This surge arrester is designed for mounting on a DIN TH-35 mm mounting rail and occupies 2 modules, allowing it to be easily integrated into an existing distribution board. Optical signaling indicates the operation of the arrester, making it easier to identify any events. It is compatible with various network configurations – TN, TN-C and TN-C-S – making it a universal solution for many applications.

This arrester is characterized by the ability to discharge impulses with a peak value of 25 kA (8/20), which ensures effective protection against most overvoltages. The protection level of 2.5 kV guarantees safe voltage limitation in the installation. Mounting on a DIN TH-35 mm rail is quick and easy, and optical signaling facilitates the identification of overvoltages and the need to replace the insert. The degree of protection IP20 provides protection against accidental contact, which is important for safety. The rated AC voltage is 400 V, making it compatible with most standard installations.

It is worth remembering that T1 surge arresters should be used in conjunction with T2 surge arresters (second stage) to ensure comprehensive protection of the electrical installation and connected devices. Proper selection of the arrester to specific operating conditions and installation characteristics is crucial to ensure its reliable operation and long-term protection.
