T2 surge arrester 20 kA N-PE 412298

Surge protection in electrical installations

This T2 surge arrester with a current of 20kA is a key element in protecting the electrical installation from the effects of overvoltages. Designed to work with type T1 arresters, it constitutes the second line of defense, absorbing the energy of the remaining surges that have passed through the first level of protection. Its task is to minimize the risk of damage to connected devices and ensure uninterrupted power supply.

Construction and application

The surge arrester is designed for mounting on a DIN TH-35 mm mounting rail, occupying only 1 module. This makes it easy to install and does not require much space in the distribution board. Designed for TN, TN-C and TN-C-S network systems, as well as other network systems. Provides L-N protection at 1.2 kV and N-PE protection at 1.5 kV. Optical indication of operation facilitates quick identification of the need to replace the insert after a surge.

Key features and benefits

• Surge protection: effectively protects the electrical installation and connected devices from the effects of lightning strikes and overvoltages from the power grid.
• High energy discharge capacity: peak discharge current of 5 kA guarantees effective protection even with strong surges.
• Versatility: compatible with various network systems (TN, TN-C, TN-C-S and others), making it an ideal solution for both new and modernized installations.
• Compact dimensions: occupies only 1 module on the DIN rail, saving space in the distribution board.
• Optical indication: informs about the operation of the arrester, facilitating diagnostics and replacement.
• Rated voltage AC 230V: adapted to standard electrical installations in residential and commercial buildings.
• Protection degree IP20: provides basic protection against accidental contact.

By choosing this T2 surge arrester, you are investing in the safety of your electrical installation and peace of mind resulting from the certainty of protection against the effects of unforeseen events. This is especially important for sensitive electronic devices that can be damaged even by small overvoltages.
