The Schneider iPRU 1P+N 20KA is a surge protection device (SPD) designed for single-phase electrical systems with neutral to protect against transient overvoltages caused by lightning strikes, switching operations, and other electrical disturbances.
Specifications:
Type: Surge Protection Device (SPD)
Model: iPRU 1P+N 20KA
Current Rating: 1P+N – Single-phase protection with neutral conductor
Maximum Discharge Capacity: 20 kA (the maximum surge current the SPD can safely handle)
Nominal Voltage (Un): Typically 230V (for single-phase systems)
Voltage Protection Level (Up): Typically 1.5 kV (the maximum voltage level the SPD will allow during surge events)
Nominal Discharge Current (In): 10 kA (the standard surge current the device can handle during typical surge events)
Rated Frequency: 50/60 Hz
Response Time: Very fast response time to ensure quick disconnect during surge events, protecting equipment from damage.
Protection Features:
Comprehensive Surge Protection: Offers protection for both live and neutral conductors, safeguarding the electrical system from transient overvoltage events.
High Surge Capacity: With a 20 kA maximum discharge capacity, the device is capable of handling large surge events, such as lightning strikes, without failure.
Thermal Disconnect: The SPD comes with a thermal disconnect feature that isolates the device if it overheats, ensuring safe operation during prolonged surge exposure.
Status Indicator: Often equipped with an indicator to show when the SPD has been triggered and needs replacement.
