MA4IMA241 is a Surgelogic MA-series surge protection module from Schneider Electric, designed for 480Y/277 VAC, 3‑phase, 4‑wire power systems. It carries a 240 kA surge current rating and is listed as a Type 1 (CSA) surge protection device, making it suitable for industrial distribution panels to guard connected equipment from voltage transients. As a replacement module for Surgelogic EMA devices, MA4IMA241 installs within MA/EMA architectures to maintain protection without replacing the entire assembly.
