The Schneider Electric A9L15684 is an Acti9 iPF65 Type 2 surge arrester — 1P+N, 230 V AC, rated for distribution networks in TN-S and TT earthing systems. The nominal discharge current is 20 kA per mode (L/N, L/PE, N/PE), with a maximum discharge of 65 kA. The voltage protection level stays under 1.5 kV for Type 2 L/N paths.
This part is marked obsolete by Schneider Electric. There is no official successor listed in the record. No direct factory drop-ship.
Type 2 classification (per EN/IEC 61643-11) means it handles induced surge currents from indirect lightning strikes — the kind that hit service-entrance or sub-distribution panels. The 20 kA nominal discharge per mode is the standard rating for a main-board SPD in a commercial or light industrial panel. The 65 kA maximum gives headroom for high-energy events. The 1.5 kV protection level means downstream equipment sees a clamped voltage below that threshold — adequate for 230 V rated gear with a 2.5 kV impulse withstand. The MOV + GDT hybrid reduces leakage current and extends service life compared to MOV-only designs.
Panel integration
Mounts via clip-on to a standard DIN rail — 4 modules wide at 9 mm pitch (36 mm total). Tunnel-type terminals accept 2.5 to 35 mm² conductors on both top and bottom. Tightening torque is 2.5 N·m. The white (RAL 9003) housing blends into a standard modular enclosure. The IK03 impact rating (per IEC 62262) is typical for enclosed panel-mount gear — not for exposed outdoor installation without a secondary enclosure.
Associated circuit breaker coordination
The manufacturer specifies a range of compatible upstream circuit breakers: IC60N, iC60H, NG125N, NG125H, or NG125L — all 50 A curve C, with breaking capacities from 10 kA to 50 kA depending on the model. This coordination ensures the SPD disconnects safely under fault without nuisance tripping. The arrester itself is not a disconnector; the breaker provides that function.
