SURGYS G50-FE

Surge arrester – Type 1 and 2 for installations with ligthning conductor and for classified sites

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 overvoltages and overvoltages 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 overvoltages.

Advantages

Recommended in case of risk of direct impact of lightning strikes

Thanks to an admitted impulse current I_imp (surge 10/350µs) of 12.5kA, 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

Indicates the end of life of varistors.

Remote signalling

The remote plug-in signalling contact allows disconnection alarm report to a supervision station.
