The Schneider Electric A9L16680 is an Acti9 iPRD8 surge arrester — a Type 2 + 3 device with a pluggable MOV cartridge, designed for electrical distribution networks in TN-C earthing systems. It occupies 4 poles (8 x 9 mm pitches) on a DIN rail and is rated for 230/400 V AC (+/- 10 %) at 50/60 Hz. The nominal discharge current is 2.5 kA per mode (L/PE, N/PE), with a maximum discharge current of 8 kA per mode and a total discharge current of 30 kA. The Type 2 + 3 classification means it handles both main surge currents (Type 2, tested with 8/20 µs waveshape) and provides voltage limiting at the equipment level (Type 3, tested with combined wave 1.2/50 µs – 8/20 µs). The open-circuit voltage [Uoc] is 10 kV in Type 3 common mode, and the voltage protection level [Up] stays under 1 kV for Type 3 N/PE — this is the let-through voltage the connected equipment sees. The maximum continuous operating voltage [Uc] is 340 V common mode (L/PE and N/PE), so it's sized for 230/400 V networks with a safety margin. The associated circuit breaker options are iC60N, iC60H, or iC60L, all 20 A curve C — the breaker provides the disconnector function and back-up overcurrent protection.
Clip-on mounting to DIN rail, 4-pole width (72 mm), 81 mm tall, 69 mm deep. Tunnel-type terminals top and bottom accept 2.5 to 35 mm² conductors; tightening torque is 2.5 N.m. Ambient operating temperature range -25 to 60 °C, storage -40 to 85 °C, relative humidity 5 to 90 %. Impact protection IK03 per IEC 62262. White housing (RAL 9003). No remote signalling contact on this variant — the pluggable cartridge has no auxiliary contact for remote monitoring. Standards compliance: EN 61643-11 and IEC 61643-11. Quality labels: KEMA-KEUR, NF, OVE.
