Schneider Electric TVS2EMA12A Surge Protection Device

Schneider Electric's TVS2EMA12A Surgelogic Surge Protection Device is a 120 kA‑per‑phase SPD designed for 208Y/120 VAC, three‑phase, four‑wire plus ground electrical systems. As part of the Surgelogic EMA external modular line, TVS2EMA12A is intended for installation in distribution panels where three‑phase protection and straightforward expansion with MA1IMA12 modules are desired in 4W+G configurations. The device delivers up to 120 kA peak surge current per phase, helping limit voltage transients that can damage equipment. Its enclosure is rated for NEMA 3R, enabling outdoor or harsh‑location installation in many commercial settings. The part number pair TVS2EMA12A and MA1IMA12 indicates the SPD module used in a multi‑pole arrangement for 208Y/120V 3Ø systems.
