Description: Model: PRD20 3P+N 20KA Type: Surge Protection Device (SPD) Poles: 3 (Three-phase) + N (Neutral protection) Rated Surge Current: 20 kA Rated Voltage: 230/400 V AC Application: The PRD20 3P+N 20KA is designed to protect three-phase electrical systems with a neutral conductor from voltage surges, often caused by lightning strikes or power grid switching. It is typically used in industrial, commercial, and residential power distribution systems to safeguard electrical equipment, motors, control panels, automation systems, and other sensitive electrical devices from transient overvoltages. Mounting: DIN rail mounted Standards Compliance: IEC 61643-1, EN 61643-11, UL 1449, CE marking Parameters: Rated Voltage (Un): 230/400 V AC (suitable for standard 3-phase, 4-wire systems) Surge Protection Level (Up): 1.5 kV Rated Surge Current (Imax): 20 kA (protection for up to 20,000 A of surge current per phase) Nominal Discharge Current (In): 10 kA (per phase) Protection Mode: 3-pole + neutral (3P+N) for full protection of the system, including the neutral conductor Response Time: ≤ 25 ns (extremely fast response to transient overvoltages) Frequency Range: 50/60 Hz Mounting Type: DIN rail mounted for easy integration into distribution panels Temperature Range: -40°C to +80°C Degree of Protection: IP20 (Protected against access to hazardous parts with a finger) Connection Type: Screw terminals for easy and secure wiring
