Strong Points
Function
SURGYS G40-FEÂ surge arresters are designed to protect your low voltage distribution systems and electrical equipment. It acts against industrial operation surges and surges owing to lightning.
This type of surge arrester is particularly recommended where there is a risk of direct impact of lightning strikes, especially at the main switchboard level when electronic devices sensitive to surges are installed.
NEW: 4 P versions compatible with IT and TT arrangements.
Conformity to standards
NF EN 61643-11, IEC 61643-11

Advantages
Recommended where there is a risk of direct impact from lightning strikes
With its max. impulse current Iimp (10/350 µs surge) of 15 kA,
it is recommended for use at the top of the installation.
Varistor / gas spark gap technology
This solution guarantees an optimised level of protection (low voltage Up=1.5 kV) and improved coordination between type 1 & type 2.
End of service life indicator
Indicates internal components' end-of-life.
Remote signalling
With the remote signalling contact (plug-in) you can upload the alert to a supervisory device.
Thermal disconnector
The surge arrester's internal disconnection device safeguards the system at the SPD's end-of-life.
All in one
Lightning and surge-voltage protection in one device
