TVS1EMA32AC - 

Overview
The Surgelogic® EMA Series surge protective device is a modular parallel transient voltage surge suppressor (TVSS). The EMA device has 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-line (L-L), line-to-ground (L-G), and neutral-to-ground (N-G). Each surge suppression mode is individually fused and uses circuitry with thermal cutouts to isolate the TVSS and ensure shutdown in the event of MOV damage during severe overvoltages, even when operated on high-fault current power systems. The suppression elements are encapsulated in a UL® Recognized potting material, another performance element that provides additional protection. A filter provides EMI / RFI noise attenuation. On-line diagnostics continuously monitor the device status, and LEDs signal a loss of a suppression circuit. An audible alarm with an enable/disable feature and dry contacts are included in the standard diagnostic package.
