Square D MA4IMA12 Surge Suppressor Module

The New Square D MA4IMA12 Surelogic Type MA_IMA Surge Protector is a 3-phase, IMA module that offers a flexible and cost effective way to achieve superior surge suppression at every level of the electrical distribution system. The modularity results in lower life cycle costs and fast, easy service or replacement. This EMA Series surge protective device features multi-stage suppression circuits consisting of field-proven, fast-acting metal oxide varistors (MOVs). A surge suppression path is provided for each mode: line-to-neutral (L–N), line-to-ground (L–G) and neutral-to-ground (N–G). Each surge suppression mode is individually fused and uses circuitry with thermal cut-outs to isolate the transient voltage surge suppressor (TVSS). It ensures shutdown in the event of MOV damage during sustained over-voltages—even when operated on high fault current power systems. This replacement surge protection module is suitable for use with safety, power management, industrial, motor drive & control, and more.
