The Schneider Electric A9L2F602 is an Acti9 iPRD F40r N-PE surge protection cartridge, Type 2+3, designed for the electrical distribution network. It handles a maximum discharge current of 65 kA common mode N/PE and a nominal discharge current of 40 kA, with a response time under 100 ns — fast enough to clamp a lightning-induced transient before it reaches downstream electronics.
Type 2+3 means this cartridge covers both main distribution board protection (Type 2) and fine protection at sub-distribution or equipment level (Type 3). The GDT (gas discharge tube) technology handles the heavy surge, while the integrated fuse ensures the arrester clears follow current — rated at 100 A — without nuisance tripping upstream MCBs. The protection level (Up) is under 1.5 kV common mode N/PE, which keeps transient voltage below the typical impulse withstand of most industrial equipment (2.5 kV for basic insulation). The temporary overvoltage rating of 1200 V for 200 ms means the cartridge won't fail on a sustained grid swell — a common failure mode in cheaper arresters. Earthing system compatibility is TT and TN-S only — not TN-C or IT. If your panel uses a TN-C combined PEN conductor, this cartridge won't work; you need a 4-pole Type 1+2 arrester instead.
This cartridge plugs into the iPRD F40r 3P or 3P+N base unit (sold separately). It's the N-PE protection mode for single-phase or three-phase TN-S and TT systems, typically installed in sub-distribution boards feeding sensitive loads — PLCs, VFDs, instrumentation loops — where the combined Type 2+3 classification eliminates the need for a separate fine-protection stage.
