SURGELOGIC™ Surge Protective Device
The XGA series is a modular parallel transient voltage surge suppressor (TVSS) designed for service entrance or downstream applications. The XGA device is a multi-stage suppression circuit consisting of field-proven, fast-acting 40 mm 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 provide normal operation during severe overvoltages and high fault current conditions. The suppression elements are encapsulated in UL® Listed and patented Ceramgard®, providing additional protection. A filter network is added to provide wave shape smoothing and a high level of EMI/RFI noise attenuation. On-line diagnostics continuously monitor the unit status and have redundant LEDs to signal a reduction in surge capacity or loss of a suppression circuit. An audible alarm with test and silence features is included in the standard diagnostic package.
