Miniature Circuit Breaker A9L08321

Description

This Acti9 iPRD8r surge arrester protects 3P 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 (between neutral and earth) is 460VAC. The Up Voltage protection level in common mode (between phase and earth) is 1.6kV in type2. The Up Voltage protection level in common mode (between phase and earth) is 1.8kV in type 3. The Ue rated operational voltage is 230VAC or 400VAC +/- 10%. The product colour is white (RAL9003).The dimensions are (W) 54mm x (H) 85mm x (D) 69mm. The weight is 340g. The degree of protection is IP20 and IP40 in modular enclosure. The operating temperature is -25ÁC to 60ÁC. The storage temperature is -40ÁC to 85ÁC. This product is compliant with EN 61643-11 and IEC 61643-11 standards.
