Advantages

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

With its max. impulse current Iimp (10/350 µs surge) of 25 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 for easy maintenance

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