Parameters: Poles: 4P (4-pole configuration, designed to protect 3-phase systems with neutral) Nominal Discharge Current (In): 100kA (the maximum surge current the SPD can safely discharge) Maximum Discharge Current (Imax): Typically higher than the nominal current, ensuring the device can handle extreme surge events (e.g., up to 200kA or higher depending on the specific model). Protection Class: Type 2 (secondary surge protection, intended for use where primary protection is in place or where moderate surge risks are anticipated) Rated Voltage (Un): 230/400V AC (standard for residential and commercial 3-phase systems) Rated Frequency: 50/60Hz Response Time: < 25ns (rapid response to transient overvoltage events) Voltage Protection Level (Up): Typically ≤ 1.5kV (maximum voltage that can appear across the SPD’s terminals during a surge) Max Continuous Operating Voltage (Uc): 275V (for AC systems) Temperature Range: -40°C to +80°C (wide operational temperature range, suitable for various environmental conditions) Degree of Protection: IP20 (protected against solid objects larger than 12mm) Mounting: DIN rail mounting for easy integration into electrical panels
