This Acti9 iPRD8 surge arrester protects 4P 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 Uc maximum continuous operating voltage in common mode (between neutral and earth) is 260VAC. The Uc maximum continuous operating voltage in common mode (between phase and earth) is 350VAC. The Up Voltage protection level in common mode (between phase and earth) is 1.1kV in type 2. The Up Voltage protection level in common mode (between phase and earth) is 1.2kV in type 3. The Ue rated operational voltage is 230VAC +/- 10%. The product colour is white (RAL9003).The dimensions are (W) 36mm x (H) 85mm x (D) 69mm. The weight is 416g. 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.
