SURGYS G40-FE 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


SURGYS G40-FE is available in X versions


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
