STC-TEL Series-RJ Connection Protection

The Sola 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 PTC technology, which consist of solid state resetable fuses.

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.


  • <1 Nanosecond Response Time
  • Solid State Silicon Breakover Technology
  • Low Capacitance
  • Over Current Protection
  • UL 497B Listed
  • Line-to-Line, Line-to-Ground Protection
  • Polyswitch Resetable Fuses PTCs
  • 5 Year Warranty
