HSP 121



The PEMCO HSP-121 Series is an advanced 3-stage hybrid, solid state power line protector. mode and normal mode suppression, nanosecond reaction time, power line tracking, and compression screw terminations make the HSP-121 Series an excellent choice in commercial and industrial applications.

The HSP-121 Series 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 HSP-121 Series demands immediate attention upon the unlikely occurrence of internal failure.
