The A9L40321 is a Schneider Acti9 iPRD Type 2 surge arrester built for IT earthing systems, rated 460 V L/PE common mode and 40 kA common mode discharge capacity across three poles, with a remote signalling contact.
Compared to the 4-pole A9L40421, the A9L40321 drops the N-PE path and the 40 kA N/PE rating, so it is the correct choice when the installation uses an IT system without a distributed neutral — the A9L40421 is for TN or TT systems that need N-PE protection.
