Specifications Parameter Specification Product Series Easy9 / PowerPact PDU (PRD series) Model PRD 80R 3P Type / Class Type 2 (Class II) – For installation at main distribution or sub-distribution level. Configuration 3 Poles (3P) – Protects the three phase conductors (L1, L2, L3). Nominal Discharge Current (Iₙ) 40 kA (8/20 µs wave, per mode). Note: "80" likely refers to the total device rating or Iₘₐₓ. Max. Discharge Current (Iₘₐₓ) 80 kA (8/20 µs wave, per mode) Voltage Protection Level (Uₚ) ≤ 2.0 kV (at Iₙ, typical for 400V systems) Rated Voltage (U꜀) 440V AC (L-L) for 400V AC three-phase systems. Key Feature "R" Integrated Thermal Disconnector: • No external backup fuse required for standard installations. • Automatically disconnects the SPD from the circuit in case of thermal overload due to end-of-life or sustained overvoltage. Status Indication Visual indicator: Green (OK) / Red (Fault/End of Life). Remote Signaling Optional remote alarm contact (often as a separate accessory). Response Time < 25 ns Mounting DIN Rail (35 mm) Width 54 mm (3-module width) Standards IEC/EN 61643-11, CE Operating Temperature -40°C to +80°C
