Acti9 iPRD Type 2 and 3 modular Surge Protection Devices protect the electrical equipments against the indirect lightning strikes.
The use of Surge Protection Devices is recommended in the case of non-critical power installations.
They are tested and rated according to the standardised current wave of 8/20 µs.

With exclusive features, Acti9 iPRD DIN rail Surge Protection Devices are geared to protect your equipments from indirect lightning strikes and improve the continuity of service.
Certified for short-circuit current withstand, Isc up to 50 kA (IEC 61643-11: 2011).
The maximum discharge current covers from 8 to 65 kA.
The maximum continuous operating voltage Uc is 350 VAC or 460 VAC.
They are suitable for any earthing system: TT, TN-S, TN-C and IT.

Withdrawable cartridges of Acti9 iPRD Surge arresters allow quick replacement of damaged devices.
It is possible to use multipolar or unipolar products for serial assembly.
The Acti9 iPRD surge arresters "r" version have dry contacts for transfering remotely the end-of-life information.

The Acti9 iPRD8 Type 3 is placed in cascade near the loads to be protected.
They should be installed in the secondary panel board, as soon as the distance from the incoming surge arrester is more than 10 meters, to ensure secondary protection.
