Notes:
ese protectors are intended for indoor use on communication loop
circuits that have been isolated from the Public Switch Telephone Network.
e communication loop circuits shall not be exposed to accidental contact with
the electric light or power conductors. e 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. e PTC increases resistance
by several orders of magnitude when over-currents
exceed safe levels. A normal state resumes when over-
currents are removed. e ability to self-restore in this
manner signicantly increases suppressor performance
and survivability.
e STC-DRS Series mounts onto a standard 35 mm
industrial DIN rail. ere are three Field Side and three
Electronics Side screw terminals. One is reserved for
a shield. ree electrically tied ground terminals are
provided for grounding the unit to building-approved
ground. e shield is isolated from ground.
