IPRU 2P 20R

The Schneider Electric Acti 9 iPRU 2P 20R is a Type 2 (Class II) Surge Protective Device designed for single-phase electrical installations. The key feature "R" indicates it has a built-in thermal disconnector, making it a "plug-and-play" SPD that typically does not require an external backup fuse. It provides protection against transient overvoltages from indirect lightning strikes and switching operations for 230V AC systems.

Specifications Parameter Specification Product Series Acti 9 iPRU Model iPRU 2P 20R Type / Class Type 2 (Class II) – For main distribution or sub-distribution protection. Configuration 2P – Protects both the Line (L) and Neutral (N) conductors in a single-phase system. Nominal Discharge Current (In) 20 kA (8/20 µs wave, per mode) Max. Discharge Current (Imax) 40 kA (8/20 µs wave, per mode) Voltage Protection Level (Up) ≤ 1.5 kV (at In, typical for 230V systems) Rated Voltage (Uc) 275V AC (L-N) for 230V AC single-phase systems (TN-S, TT). Key Feature Integrated Thermal Disconnector ("R" version): • Eliminates the need for an external backup fuse in standard installations. • Automatically disconnects the SPD from the circuit in case of thermal overload due to end-of-life or sustained overvoltage. Status Indication 3-color LED indicator: • Green: Functional • Orange: Pre-alarm / End of Life approaching • Red: Faulty / Disconnected Remote Signaling Built-in changeover contact (NO/NC) for connection to a BMS or alarm panel. Mounting DIN Rail (35 mm) Width 36 mm (2-module width) Standards IEC/EN 61643-11 Operating Temperature -40°C to +80°C
