SURGYS G100-F
Types 1 and 2 for installations with ligthning conductor and for classified sites
The SURGYS G100-F surge arrester is designed to ensure the protection of your low voltage distribution installations and your electrical equipment. It acts against industrial operation overvoltages and overvoltages owing to lightning. This type of surge arrester is particularly recommended in case of risk of direct impact of lightning strikes.
Advantages
Recommended where there is a risk of direct impact from lightning strikes
It is recommended for use at the top of the installation, due to its max. impulse current Iimp (10/350μs wave) of 25 kA.
Absence of follow current
The multi-varistor technology ensures there is no line follow current and avoids any risk of nuisance tripping of upstream protection devices.
Integrated thermal disconnection device
Guarantees disconnection at surge arrester's end of life.
End of service life indicator
Indicates varistor’s end-of-life.
Remote signalling
The remote signalling contact provides disconnection data to a supervision station (BMS).
Plug-in modules for easy maintenance
These modules are quick and easy to replace, without having to uncable the device.

Applications
• Located in the main switchboard, upstream of the distribution panels.
• Main electrical switchboard + building protected against lightning either:
- through lightning conductors
- through mesh cages.
• Main switchboard in buildings subject to a high risk of lightning strikes such as classified installations, installations located in areas prone to a high density of lightning strikes,
high-rise buildings, presence of antenna towers, chimneys.
• Sites located at high altitude.
• Distribution board of a building with presence of Lightning Protection Systems.
