SCHNEIDER ELECTRIC A9L40172 - Modular Surge Protective Device
The SCHNEIDER ELECTRIC A9L40172 is a modular Type 2 Surge Protective Device (SPD) from the Acti 9 iPRD40r series, engineered for robust protection of low voltage electrical installations against transient overvoltages. This 3P+N device integrates Metal Oxide Varistor (MOV) technology to divert surge currents, safeguarding sensitive industrial equipment and control systems from indirect lightning strikes and switching transients. It is designed for DIN rail mounting within industrial control panels, distribution boards, and building infrastructure, providing both local and remote status indication.
