This Acti9 iPRD8r surge arrester protects 3P+N installations. It allows quick replacement of damaged cartridges.::The Imax maximum discharge current is 8kA .The In nominal discharge current is 2.5kA.::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.::The surge arresters with "r" indication have remote transfer of the information "Cartridge to be replaced".::The Uc maximum continuous operating voltage in common mode is 260VAC between neutral and earth, and is 350V between phase and earth.::The Up Voltage protection level in common mode is 1.4kV between neutral and earth in type 2, and 1.1kV between neutral and earth in type 3.::The Up Voltage protection level in differential mode (between phase and neutral) is 1kV in type 2, and 1.1kV in type 3.::The Ue rated operational voltage is 230VAC +/- 10%.::The product colour is white (RAL9003).The dimensions are (W) 72mm x (H) 85mm x (D) 69mm. The weight is 421g.::The degree of protection is IP20 and IP40 in modular enclosure.::The operating temperature is -25°C to 60°C. The storage temperature is -40°C to 85°C.::This product is compliant with EN 61643-11 and IEC 61643-11 standards.
