Schneider Electric 237 200 Series Surge Protective Device, 120VAC, 15.5 kA (FAS-120AC)

Protect critical security, surveillance and monitoring systems with the Schneider Electric FAS-120AC surge protective device. Designed for panel-level protection of 120VAC distribution circuits, this compact surge suppressor guards sensitive electronics against damaging transients with a 15.5 kA surge-handling capability. The PowerSure FAS-120AC combines fast-response MOV technology with thermal fusing to stop sustained faults, while an LED status indicator provides a clear visual health check for maintenance teams. Engineered for easy parallel installation on single-phase L, N, G circuits and finished with a liquid-tight conduit fitting, it fits neatly into crowded panels without sacrificing performance. Whether protecting network switches, NVRs, cameras, access control power supplies or other low-voltage devices, the FAS-120AC reduces equipment downtime and replacement costs. Backed by Schneider Electric quality and a 5-year limited warranty, it’s an economical choice for integrators and facilities managers who prioritize uptime and predictable maintenance. Add the FAS-120AC to your next security or IT power protection plan to strengthen resilience and simplify serviceability.
