The Schneider IPRF1 12.5GN, 3P+N is a Surge Protection Device (SPD) designed for protecting electrical installations against transient overvoltages, such as those caused by lightning strikes or switching surges. It is part of Schneider Electric's IPRF1 series, offering a high level of protection for 3-phase systems with neutral (3P+N).
Parameters:
Poles: 3P+N (3-phase + neutral configuration)
Nominal Discharge Current (In): 12.5kA (the maximum surge current the device can safely discharge)
Maximum Discharge Current (Imax): Typically higher than the nominal current (e.g., up to 25kA or higher depending on the specific model).
Protection Class: Type 2 (secondary protection, suitable for use in environments where primary protection is already in place or where lower levels of surge risk are present).
Rated Voltage (Un): 230/400V AC (for standard 3-phase systems)
Rated Frequency: 50/60Hz
Voltage Protection Level (Up): Typically ≤ 1.5kV (maximum voltage that appears across the SPD during a surge event)
Max Continuous Operating Voltage (Uc): 275V (for AC systems)
Response Time: < 25ns (very fast response to transient surges, minimizing the risk to connected equipment)
Temperature Range: -40°C to +80°C (suitable for a wide range of environmental conditions)
Degree of Protection: IP20 (protected against solid objects larger than 12mm)
