Power Protection and Conditioning
STC-TEL Series – RJ Connection Telephone Protection
The SolaHD STC-TEL series are single pair telephone or
Data Line Protectors that use an advanced two-stage hybrid
design. These units address over voltage transients with
silicon breakover devices, while sneak and fault currents are
mitigated with resetable fuses (PTCs).
These units use two screw terminals to connect a Telco line
to the protector. The equipment to be protected then plugs
into the female modular jack on the STC-TEL.
