Specifications: Type: Surge Protection Device (SPD) Number of Poles: 3P+N (3 poles + neutral) – Suitable for three-phase systems with neutral conductor Maximum Discharge Capacity: 40 kA (the maximum fault current the SPD can safely handle) Nominal Voltage (Un): Typically 400V (for three-phase systems) Voltage Protection Level (Up): Typically 1.5 kV (the maximum voltage the SPD will allow) Nominal Discharge Current (In): 20 kA (the standard surge current the SPD can handle) Rated Frequency: 50/60 Hz Response Time: Fast response time to ensure minimal damage from transient overvoltage events. Protection Features: Complete Surge Protection: Protects both live and neutral conductors, providing full protection for the electrical installation. High Surge Capacity: With a 40 kA discharge capacity, it is capable of handling high-energy surges, ensuring that your equipment is protected from major surge events. Thermal Disconnect: Integrated thermal disconnect feature that automatically isolates the SPD if it overheats, enhancing safety during fault conditions. Compliance: Complies with international standards such as IEC 61643-1 for surge protection devices and IEC 60364-5-53 for low-voltage electrical installations.
