It's a single-pole (1P) MOV-based unit rated for 230 V AC (+/- 10 %) at 50/60 Hz, designed to clamp transient overvoltages on the electrical distribution network. The key numbers for fit: a nominal discharge current of 20 kA (common mode L/PE) and a maximum discharge current of 65 kA (common mode L/PE). The voltage protection level [Up] is under 2.3 kV (type 2, L/PE). It clips onto a DIN rail (clip-on mounting mode) and occupies 18 mm width (2 x 9 mm pitches) on the rail, with a depth of 69 mm and height of 85 mm. The housing is white (RAL 9003). ## Where it fits and key ratings This surge arrester is designed for IT earthing systems, which is the ungrounded or high-impedance grounded system common in hospitals, industrial plants, and data centers where continuity of service is critical. The maximum continuous operating voltage [Uc] is 460 V L/PE (common mode). Temporary overvoltage [Ut] withstand is 337 V L/N for 5 seconds, and 1455 V L/PE for 200 ms in safe failure mode. The short-circuit withstand rating is 5 kA at 415 V phase-to-phase. The manufacturer specifies associated disconnectors: an iC60L 25 A curve C (Icu 25 kA), NG125H or NG125L 50 A curve C (Icu 36 kA or 50 kA), or a gG fuse 80 A (Icu 50 kA). This means the arrester must be paired with one of these upstream devices for proper fault coordination. Terminals are tunnel type, accepting 2.5 to 25 mm² rigid or 4 to 16 mm² flexible (with or without ferrule). Wire stripping length is 14 mm, tightening torque 3.5 N.m. Operating temperature range is -25 to 60 °C, storage -40 to 85 °C, with relative humidity 5 to 95 %. Maximum operating altitude is 2000 m. ## Signalling and compliance This unit includes remote signalling via a 1 C/O (changeover) contact rated 0.25 A / 250 V AC. The ground residual current [Ipe] is 0.6 mA. Standards compliance covers EN 61643-11:2012 and IEC 61643-11:2011, which define the testing and performance requirements for low-voltage surge protective devices.","metaTitle":"Schneider Electric A9L65121 Acti9 iPRD65r Type 2 Surge Arres","metaDescription":"Schneider Electric A9L65121 Acti9 iPRD65r Type 2 surge arrester, 1P, 65 kA max discharge, 230 V AC, MOV, clip-on DIN rail.
