FIRE & SECURITY SURGE PROTECTORS
HSP-121BT Series
Description
The
HSP121BT-1RU is an advanced 3 stage hybrid, solid state power line surge protector. Features such as noise filtering, common mode and normal mode suppression, nanosecond reaction time, power line tracking, and compression screw terminations, make the
HSPI21BT-1RU an excellent choice in commercial and industrial applications.
The HSP121BT-1RU 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
HSP121BT-IRU demands immediate attention upon the unlikely occurrence of internal failure.

Installation
- Mount HSP121BT-1RU in a UL Listed Housing
- Make sure wiring from power sources properly connects to line side of HSP. Wiring from protected equipment must properly connect to EQUIP side of HSP.
- Indication of internal failure:
a. Indicator will extinguish
b. Fuse blown will disconnect load from power source.
WARNING: For continued protection against risk of fire, replace only with same type rating of fuse.
- Connect only to 120 VAC, 15 Amp max., single phase, three wire circuit.
