Surge arrester T1 35 kA 1P IT-440V 412280

Electrical installation protection with Legrand surge arrestors

This single-pole type T1 surge arrester with a surge current of 35kA is a key element in protecting the electrical installation from the effects of lightning strikes and overvoltages. It provides protection in IT, TN-C, TN-C-S and TN networks, making it a universal solution for various applications. Its task is to minimize the risk of damage to electrical and electronic devices, as well as to prevent fires caused by overvoltage.

Construction and application

The arrester is designed for mounting on a TH-35 mm DIN rail, occupying only 2 modules. This makes it easy to install and does not require much space in the distribution board. Adapted for conductors with a maximum cross-section of 35 mm², which allows its use in both domestic and industrial installations. Optical signaling informs about the operation of the device, making it easier to identify potential problems. An additional contact for remote signaling enables integration with monitoring and alarm systems.

Key features and benefits

• Versatility: Compatible with various network systems (IT, TN-C, TN-C-S, TN), eliminating the need to have many different models of surge arrestors.
• High efficiency: Rated discharge current of 25 kA (peak value) and a protection level of 2.5 kV guarantee effective protection against overvoltages.
• Easy diagnostics: Optical indication of the device status facilitates quick identification of any failures or the need for replacement.
• Remote monitoring: Thanks to the remote signaling contact, it is possible to integrate with electrical installation monitoring systems.
• Compact dimensions: Occupies only 2 modules on the DIN rail, allowing you to save space in the distribution board.
• Safety: Compliance with standards ensures safe and reliable operation of the device in various operating conditions.
• Universality: Designed to protect circuits with a rated voltage of 400V and a maximum operating AC voltage of 440V.

This arrester is a solid solution for anyone who cares about the safety of their electrical installation and wants to avoid costly repairs caused by overvoltages. This is especially important in areas prone to frequent storms or in places connected to an unstable power grid.
