ACData’s AC21SM provides affordable hardwired AC surge suppression solutions. Compact size and robust hybrid design make the AC21SM an ideal solution for use in integrated load centers, as well as stand-alone surge protection applications.

ACData’s innovative Advanced Coordinated Hybrid™ technology combines silicon avalanche diodes (SADs) and metal oxide varistors (MOVs) to provide unmatched protection from transient voltage surges. Each phase includes an LED status indicator allowing visual verification of protection status. LED “on” indicates suppressor is functional. LED “off” indicates suppressor or AC power failure. Form C contacts are included. Optional flush mount faceplate available.
