This Acti9 iPRD8 surge arrester protects 1P+N installations. It allows quick replacement of damaged cartridges.
The Up Voltage protection level in CM common mode (between phase and neutral) is 1.1kV.
The iPRD8r ensures secondary protection of loads to be protected and is placed in cascade with the incoming surge arresters.
This surge arrester is required when the loads to be protected are at a distance of more than 10 m from the incoming surge arrester.
