Very Heavy Duty Data Line Surge Suppressor

The TSS-300 should be specified to protect electronic equipment that uses an 8-pin modular connector to connect to the data line/network. The TSS-300 provides protection on pins 1 and 2 (transmit data) and pins 7 and 8 (receive data) of the modular jack interface.

Optional 18" RJ-48 jumper cable is part number CBL-300-18.

The TSS-300 is a very heavy duty data line surge suppressor designed to protect sensitive electronic equipment from damage caused by voltage transients. The TSS-300 is designed to protect equipment connected to high-speed data channels such as SynchroNet® DSU-CSUs, DATAPHONE® DDS, and local area data networks.

What distinguishes the TSS-300 from other suppressors is our unique three-stage design. Very high speed bi-directional SIDACTORsTM work in combination with MOVs and three-element heavy-duty gas discharge tubes to provide a suppressor that has an extremely fast response time yet can also dissipate large amounts of energy. Inter-stage wirewound resistors provide better surge current handling than competing carbon-film designs. Wide PC board traces and ground planes provide additional surge handling capability.
