Surge arrester T2 20 kA 1P+N 412226

### Protection of electrical installations against overvoltage

This T2 surge protector, with a discharge current of 20 kA, is a key element in protecting electrical installations in residential and commercial buildings. It provides protection against the effects of lightning strikes and other overvoltages, minimizing the risk of damage to electrical and electronic equipment. This is particularly important in areas prone to frequent storms or with an unstable power grid.

This surge protector belongs to the ON300 series from Legrand, which is highly regarded by installers for its reliability and ease of installation. The 1P+N design means it protects both the phase and neutral conductors, increasing the effectiveness of the protection. Optical indication of the device's status allows for quick identification of the need to replace the insert.

Characteristics and application

This surge protector is designed for mounting on a DIN TH-35 mm mounting rail, which facilitates its integration with the existing electrical distribution board. Its compact size – 2 modules – saves space in the switchgear cabinet. Compliance with IEC/EN 61643-11 standards guarantees its safety and effectiveness.

The device is suitable for use in TN-C, TN-C-S, TN and TT networks. The maximum conductor cross-section of flexible conductors up to 25 mm² and rigid conductors up to 35 mm² ensures compatibility with various types of cabling. The L-N protection level is 1.2 kV and N-PE is 1.5kV, providing effective protection against overvoltages.

Key features and benefits
