The Schneider Electric Acti 9 iPE iPC iEC 2 20 4P 20kA refers to a modular Type 2 Surge Protective Device (SPD) from the Acti 9 iPE, iPC, or iEC series (depending on specific product line and region). This 4-pole, 20kA per mode SPD is designed for main or sub-distribution board protection against transient overvoltages from indirect lightning strikes and switching operations in three-phase electrical systems.
