Parameters: Poles: 4P (4 poles, used for protecting both phase and neutral in a 3-phase system) Nominal Discharge Current (In): 80kA (maximum current that the SPD can handle during a surge event) Maximum Discharge Current (Imax): Typically higher than the nominal current, ensuring the SPD can withstand extreme surges (e.g., up to 160kA or higher depending on the model). Protection Class: Type 2 (secondary protection, designed for use in installations where Type 1 protection has already been implemented or where surge risks are moderate) Rated Voltage (Un): 230/400V AC (standard voltage for residential and industrial electrical installations) Rated Frequency: 50/60Hz Response Time: < 25ns (fast response time to prevent damage from fast-rise surges) Voltage Protection Level (Up): Typically ≤ 1.5kV (the maximum voltage that will appear across the SPD during a surge) Max Continuous Operating Voltage (Uc): 275V (AC systems) Temperature Range: -40°C to +80°C (suitable for a wide range of environmental conditions) Degree of Protection: IP20 (protection against solid objects larger than 12mm) Mounting: DIN rail mountable for easy integration into electrical distribution boards
