Function and Application
The NU5-Ⅰ+Ⅱ Surge Protective Device complies with the GB/T 18802.11 standard. It is suitable for AC 50Hz, rated voltage of single-phase 230V / three-phase 400V power distribution and control systems, and meets SPDI and SPDII level tests. It is used to suppress transient overvoltage below the equipment's impulse withstand voltage, and to discharge surge energy, thereby protecting the system circuit and equipment. The main functions and features of the surge protective device: it has L-PE, N-PE, L-N protection modes, suitable for various power grid systems; it has aging overheating protection, body degradation indication, uses an insert structure, and can be optionally equipped with a remote alarm function
