Introduction
The STCHSP121BT1RU is an advanced 3-stage hybrid, solid state power line protective device. Features
such as noise ltering, common mode and normal mode suppression, nanosecond reaction time, power line
tracking, and compression screw terminations, make this device an excellent choice in commercial
and industrial applications.
This SPD offers a replaceable fuse designed to remove the load from the line in the event the unit is overloaded
or the internal protection stops working.
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

enclosure. (Reference Figure 1.)
4. Using a slotted screwdriver, turn the fuse cover 1/4 turn clockwise, this will free the fuse cover.
5. Remove the existing fuse and replace with same type rating of fuse (3 AB,15 A/250 V).
6. Replace all devices, doors, and covers before turning on power to the equipment.
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E,
