Types 1 and 2 for installations with ligthning conductor and for classified sites (sensitive equipment)

The SURGYS G50-FE surge arrester is designed to ensure the protection of your low voltage distribution installations and your electrical equipment. It acts against industrial operation surges and surges owing to lightning. This type of surge arrester is particularly recommended in case of risk of direct impact of lightning strikes, at the main switchboard level containing electronic devices sensitive to surges.
NEW: version for TT arrangement mains.


Recommended where there is a risk of direct impact from lightning strikes

With its max. impulse current Iimp (10/350μs surge) of 12.5 kA, it is recommended for use at the top of the installation.

Absence of line follow current

The multi-varistor technology ensures there is no 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 and monobloc base for easy installation and maintenance

These modules are quick and easy to replace, without having to uncable the device.
