Surge arrester T1+T2 8/50 1P+N 412256

Electrical installation protection with Legrand ON300 surge protectors

A T1+T2 surge protector is a key element in protecting the electrical installation from the effects of lightning strikes and voltage surges in the network. The 1P+N model from the ON300 series by Legrand provides comprehensive protection, combining the features of a Type T1 surge protector (protection against direct lightning strikes) and Type T2 (protection against indirect effects of lightning and voltage surges in the network). This is an ideal solution for both home and commercial installations where reliability and safety are a priority.

Design and application

This surge protector is designed for mounting on a DIN TH-35 mm mounting rail, which simplifies its installation in electrical switchboards. The compact size – only 2 modules – allows for saving space. It is intended for TN-C, TN-S, TT and TN-C-S networks, making it a universal solution for different types of installations. Optical indication of the operating status facilitates quick identification of the need to replace the surge protector after a voltage surge.

Performance and parameters

This surge protector is characterized by a rated AC voltage of 230 V and the ability to dissipate a peak discharge current of 20 kA (8/20 µs). The L-N protection level is 2 kV, and N-PE is 1.5 kV, which guarantees effective protection of sensitive electronic devices. The maximum cross-section of flexible conductors is 25 mm², and rigid conductors – 35 mm², which ensures compatibility with most wiring used in buildings. Thanks to this, these surge protectors will be useful in protecting a variety of equipment, from lighting to advanced home automation systems.
