Function
SURGYS G50-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 arrestor is particularly recommended in case of risk of direct impact of lightning, at the level of the main switchboard with electronics prone to overvoltages.
NEW: version for TT arrangement networks.
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 12.5 kA,
it is recommended for use at the top of the installation.
Absence of follow current
The multi-varistor technology ensures there is no line sequence 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.
