STC-DRS Series
Introduction
The STCDRS036 is a DIN Rail mountable, single pair surge suppression module implementing three stage
hybrid technology. This module addresses over-voltage transients with gas tubes and silicon avalanche
components. In addition, sneak currents are mitigated with resetable fuses (PTCs). The PTCs increase
resistance several orders of magnitude when over-currents exceed operating limits. A normal state resumes
when the over-current condition is removed. The ability to self-restore in this manner significantly increases
suppressor performance and survivability.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E,
NOM-029-STPS or CSA Z462.
• This equipment must only be installed and serviced by qualified electrical personnel.
• Turn off all power supplying this equipment before working on or inside equipment.
• Always use a properly rated voltage sensing device to confirm power is off.
• Replace all devices, doors and covers before turning on power to this equipment.
• This equipment must be effectively grounded per all applicable codes. Use an equipment-grounding conductor to
connect this equipment to the power system ground.
• Confirm that the Surge Protective Device voltage rating on the module or nameplate label is not less than the
operating voltage.
• For 6-35VDC models, do not place in service on any signal line capable of continuously supplying
more than 150mA.
Failure to follow these instructions will result in death or serious injury.
