Edco HSP-121A Series

$125.39

Edco HSP-121A Series External Mount 120 VAC Protection.  The Edco HSP-121A is a UL 1449 Listed, three-stage power line protector.  Features include noise filtering, NEMA-4X enclosure, common mode and normal mode protection.

In addition, the HSP-121A can be installed using conduit fittings and can be mounted inside or outside of electronic enclosures.  The Edco HSP-121A offers a replaceable fuse designed to remove the load (protected equipment) from the line if the unit is either overloaded or the internal protection fails.  This feature prevents surges from entering equipment through a failed protector, not noticed by the user. Unlike models with only an indicator, which may take weeks to notice, the HSP121A demands immediate attention upon the unlikely occurrence of internal failure.
