This Domae surge arrester protects 3P+N residential and larger buildings installations against indirect transient overvoltages. The Imax maximum discharge current is 40kA. The In nominal discharge current is 15kA. It protects electrical installations against direct lightning strikes. The Uc maximum continuous operating voltage in common mode is 260VAC between neutral and earth, and 340VAC between phase and earth. The Uc maximum continuous operating voltage in differential mode (between phase and neutral) is 340VAC. The Up Voltage protection level is 1.5kV. The Ue rated operational voltage is 230VAC or 400VAC +/- 10%. The operating frequency is 50Hz or 60Hz. The product colour is white (RAL9003).The dimensions are (W) 72mm x (H) 81mm x (D) 63mm. The weight is 420g. The degree of protection is IP20 on its terminals becoming IP40 once in modular enclosure. The operating temperature is -25°C to 60°C. The storage temperature is -40°C to 70°C. This product is compliant with EN 61643-11 standard.
