IPRU 3P+N 40KA

The Schneider IPRU 3P+N 40KA is a Surge Protection Device (SPD) designed to protect electrical installations from transient overvoltage events, such as lightning strikes or switching surges. It is particularly effective in providing protection for 3-phase systems with neutral (3P+N), and it has a high capacity for handling surge currents.

Parameters: Poles: 3P+N (3-phase + neutral) Nominal Discharge Current (In): 40kA (maximum surge current the SPD can safely discharge) Maximum Discharge Current (Imax): Typically higher than the nominal current, ensuring the device can withstand extreme surges (e.g., up to 80kA or higher, depending on specific model variants). Protection Class: Type 2 (Secondary surge protection, designed for systems that are already protected by a primary SPD, or for lower-risk systems) Rated Voltage (Un): 230/400V AC (for standard 3-phase systems) Rated Frequency: 50/60Hz Response Time: < 25ns (a very fast response to protect against fast-rise surges) Voltage Protection Level (Up): Typically ≤ 1.5kV (indicates the maximum voltage that will appear across the SPD's terminals during a surge) Installation Category: Class II (providing protection in a secondary position in the surge protection hierarchy) Degree of Protection: IP20 (protected against solid objects larger than 12mm) Temperature Range: -40°C to +80°C Nominal Voltage (Un): 230V (for single-phase) / 400V (for 3-phase systems) Max Continuous Operating Voltage (Uc): 275V (for AC systems) Mounting: DIN rail mounting for easy integration into distribution boards
