Schneider Electric ma4ima12 Surge Protective Device

Schneider Electric MA4IMA12 is a Surgelogic surge protection module (SPD) engineered for 480Y/277 VAC, 3-phase, 4-wire distribution systems. This Type 2 SPD delivers up to 120 kA peak surge current, providing robust transient suppression for downstream equipment in industrial or commercial panels. As part of the Surgelogic MA family, the MA4IMA12 can function as an external protection module within MA-series installations and is commonly used to extend or replace protection in existing MA protectors, ensuring continued surge protection performance. It is intended for 480Y/277 VAC operation with a grounded neutral, safeguarding equipment such as controllers, drives, sensors, and other critical electronics from voltage spikes generated by lightning or switching events. The 3-phase, 4-wire configuration aligns with standard distribution panel layouts, enabling straightforward integration into Schneider Electric's protection strategy and coordinated protection with other MA-series devices.
