Schneider Electric 237 ASCO 200 Series 120VAC Medium Duty (Parallel) AC-Hardwire Surge Suppressor

Protect sensitive equipment in security, surveillance, and IT environments with the Schneider Electric 237 ASCO 200 Series 120VAC Medium Duty (Parallel) AC-Hardwire Surge Suppressor. This surge protection module is engineered to clamp damaging transients on standard single-phase 120 VAC (L, N, G) circuits, helping reduce downtime and avoid premature equipment failure across access control panels, network switches, DVR/NVRs and servers. Integrated metal-oxide varistors (MOVs) and thermal fusing provide fast response and fail-safe disconnection under sustained surge conditions, while visible LED indication simplifies status monitoring for maintenance teams. The unit delivers comprehensive L–G, L–N and N–G protection in a compact package that fits neatly inside distribution panels and pairs with liquid-tight conduit fittings for clean installations. With fast MOV response time and a 5-year warranty, the 237 model balances cost-effective medium-duty protection with the reliability required by critical monitoring and security systems. Specify this Schneider Electric surge protection module for retrofit or new builds where preserving uptime of surveillance, monitoring and networking equipment is essential.
