Notes:
These protectors are intended for indoor use on communication loop
circuits that have been isolated from the Public Switch Telephone
Network.
The communication loop circuits shall not be exposed to accidental
contact with the electric light or power conductors. The protectors
shall be installed per the applicable requirements of the National
Electric Code, ANSI/NFPA 70.
Using three-stage hybrid technology, this DIN Rail mountable, single pair, surge suppressor attenuates over-voltage
transients with gas tubes and silicon avalanche components
while resetable fuses (PTCs) mitigate sneak currents. The
PTC increases resistance by several orders of magnitude
when over-currents exceed safe levels. A normal state
resumes when over-currents are removed. The ability to
self-restore in this manner signicantly increases suppressor
performance and survivability.
The STC-DRS Series mounts onto a standard 35 mm
industrial DIN rail. There are three Field Side and three
Electronics Side screw terminals. One is reserved for a
shield. Three electrically tied ground terminals are provided
for grounding the unit to building-approved ground. The
shield is isolated from ground.
