Schneider Electric MA4IMA24 Surge Protective Device

Schneider Electric MA4IMA24 Surgelogic IMA Surge Protection Device is a Type 2 externally mounted surge protection module designed for 480Y/277 VAC, three‑phase, four‑wire power systems. As a replacement MA module, MA4IMA24 is used to update or restore protection in Surgelogic MA devices, preserving high‑energy surge suppression in industrial electrical environments. It operates over a frequency range of 47–63 Hz and is specified for 480Y/277 V configurations, providing protection against transient overvoltages that can damage motors, drives, and control electronics. The unit carries a short‑circuit current rating up to 200 kA SCCR, making it suitable for demanding installations while maintaining 3P4W connectivity for phases A, B, and C with a neutral/ground reference. This surge protection module is part of Schneider Electric’s Surgelogic family, engineered for robust, externally mounted protection in commercial and industrial applications, and designed to integrate with existing EMA/IMA surge protection schemes to deliver continuous protection across the distribution network.
