The iPF surge arresters with “r” indication have remote transfer of the information: “surge arrester to be replaced”.
Acti 9 iPF & iPRD
Surge protection device
Acti 9 iPF K & iPRD Type 2 Surge Protection Devices protect the electrical equipment against indirect lightning strikes.
The use of Type 2 Surge Arresters is recommended in the case of non-critical power installations.
They are tested and rated according to the standardized current wave of 8/20 µs.
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 has dry contacts for transferring remotely the end-of-life information.
The Acti9 iPRD8 Type 3 is placed in a cascade near the loads to be protected.
They should be installed in the secondary panelboard, as soon as the distance from the incoming surge arrester is more than 10 meters, to ensure secondary protection.
With exclusive features, Acti 9 iPF & iPRD DIN rail type-2 Surge Protector Devices (SPDs) are definitely geared to absolute safety and improved continuity of service.
- Class-2 insulation: continuous safety for operators and unqualified personnel.
- VISI-TRIP: detects faulty type-2 Surge Protector Devices (SPDs) outgoers quickly and reduces intervention time.
