GearHSP121A
120VAC—NEMA 4X

The 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 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.
