TLT Series

Telephony Lines Surge Protection Device

The TLT Series is a Secondary Transient Voltage Surge Suppression for Telephony line protocols. Units provide protection against Transient Voltages that exceed the nominal operating voltage of Dial-Up, Dedicated/Leased and T1 Lines.

Each line is protected against surge current impulses up to 1.9kA/wire. The TLT Series installs in series with the telephone lines to be protected, diverting harmful transient energies to ground while maintaining close clamping thresholds above normal service voltages. Units can be configured for all standard telephony applications by varying circuit components and/or densities.

The SG housing for the TLT Series is designed for indoor and outdoor installations. All other housings are for indoor use only.

  • Solid state fail-safe design

  • Low shunt capacitance to reduce signal loss

  • Performance tested to verify compliance

ETL Listed to UL497A Standard. (Secondary protection for Telephone Lines)

Replace XX with number of wires to be protected: 02 = 2 wires, 04 = 4 wires, 06 = 6 wires, 08 = 8 wires, 10 = 10 wires.

Replace ZZ with: RJ for Modular Jacks (female to female) - TS for Terminal Strip Screw

Modular Jacks: only 8 wires for case A & B. Case G only 6 wire.
