Surge arrester – Type 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 in case of risk of direct impact of lightning strikes
Thanks to an admitted impulse current Iimp (surge 10/350µs) of 25 kA, it is recommended for use on main switchboards.
Absence of follow current
The multi-varistors technology ensures there is no follow currents and prevents from any risk of inadvertent tripping of input protections.
Thermal disconnection device
Guarantees the end of service life disconnection of the surge arrester.
End of service life indicator
End of service life indication for internal components.
Remote signalling
The remote plug-in signalling contact allows disconnection alarm report to a supervision station.
Monobloc base with plug-in module
The SURGYS is supplied complete and ready for installation. Its Monobloc base is fitted with replaceable plug-in modules which, at the end of their service life, can be easily and quickly replaced without having to disconnect the Monobloc base.
• Upstream location of the distribution surge arresters.
• TGBT + building protected against lightning either:
– through lightning conductors
– through mesh cages.
• TGBT in buildings subjected to high level risk of lightning strikes such as classified installations, installations located in areas prone to 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.
