This Acti9 iPRD1 12.5r surge arrester protects 1P+N residential and small commercial buildings installations against direct and indirect transient overvoltages. This type 1+2 device autoprotected by an integrated circuit-breaker is recommanded for high risk level in incoming panel board. It offers remote reporting of the "cartridge must be changed" message. This prewired surge arrester allows quick replacement of withdrawable cartridges when they are damaged. It incorporates its end of life safety disconnector. This Acti9 iPRD1 12.5r is compatible with TT and TN-S earthing systems. Associated with Compact NSXm H TM80D the breaking capacity is 70kA. The Imax maximum discharge current is 50kA. The In nominal discharge current is 20kA. The Uc maximum continuous operating voltage in differential mode (between phase and neutral) is 350VAC. The Uc maximum continuous operating voltage in common mode is 255VAC between neutral and earth. The Up Voltage protection level is 1.5kV type 1+2. The Ue rated operational voltage is 230VAC. The operating frequency is 50Hz. The dimensions are (W) 36mm x (H) 89mm x (D) 69mm. The width in 9mm pitches is 4. The weight is 290g. 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 +80°C. This product is complies with EN 61643-11 2012 and IEC 61643-11 2011 standards.
