The A9L08100 is a Schneider Electric Acti9 iPRD8 Type 2+3 surge arrester, single-pole, rated 230 V AC and 350 V maximum continuous operating voltage.
Tunnel terminals on both sides accept 2.5 to 35 mm² conductors; torque to 2.5 N·m. The white RAL 9003 housing matches the rest of the Acti9 family, so it blends into a populated panel without a visual mismatch.
Rated as a Type 2+3 arrester per EN 61643-11:2012 and IEC 61643-11:2011. It uses MOV technology and handles a maximum discharge current of 8 kA common mode (L/PE) and a nominal discharge of 2.5 kA. The voltage protection level stays under 1 kV type 3 L/PE. Temporary overvoltage withstand is 337 V L/N for 5 seconds, and 1200 V N/PE for 200 ms in safe failure mode. Ground residual current is 0.003 mA (0.6 mA). IK03 mechanical impact rating per IEC 62262. Quality labels include NF and KEMA-KEUR.
