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
