Product details

This is a Schneider Electric Acti9 iPRD Type 2 surge arrester, order code A9L16574. It's a 3-pole-plus-neutral unit rated 230/400 V AC, built for TT and TN-S earthing systems. The pluggable cartridge uses MOV + GDT technology and clips onto a DIN rail — standard panel integration for distribution boards.

Type 2 per EN 61643-11 / IEC 61643-11. Maximum discharge current is 20 kA common and differential mode. Nominal discharge current is 5 kA. Maximum continuous operating voltage is 340 V AC for L/PE and L/N, and 260 V AC for N/PE. Voltage protection level is under 1.4 kV. Operating temperature range is -25 to 60 °C, storage from -40 to 85 °C, relative humidity 5 to 90 %. Rated for installation up to 2000 m altitude. IK03 impact rating per IEC 62262.

Mounts on DIN rail via clip-on. Dimensions: 81 mm high, 72 mm wide, 69 mm deep — occupies 8 modules of 9 mm pitch on the rail. The tunnel-type terminals accept 2.5 to 35 mm² conductor on both top and bottom; tightening torque is 2.5 N.m. The associated circuit breaker options are iC60N, iC60H, or iC60L, all 25 A curve C, with interrupting ratings of 10 kA, 15 kA, or 25 kA respectively. That breaker is required upstream for overcurrent protection and disconnection.
