Features
 • 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
 • The maximum discharge current covers from 8 to 65 kA
 • The maximum continuous operating voltage Uc is 350 VAC or 460 VAC
 • 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
 • In a building with a height greater than 10 meters, with several dwellings, if a Type 1 surge arrester is installed in the main electrical switchboard, a Type 2 surge arrester must also be installed at the head of each divisional switchboards in order to distribute the constraints
 • In every new house without a lightning rod (primary protection) it is now mandatory to install in the electrical switchboard a Type 2 Surge Protection Device

Applications
 • Acti9 iPRD Type 2 Surge Protection Devices protect the electrical installations in all industrial and tertiary buildings against induced or conducted surges caused by indirect lightning strikes
 • These Type 2 Surge Protection Devices can be used also for the protection of residential installations
 • They are suitable for any earthing system TT, TN-S, TN-C and IT

Specifications

 • Certified for short-circuit current withstand, Isc up to 50 kA (IEC 61643-11: 2011)
