Transtector Data & Signal Surge Protectors

Transtector Data and Polyphaser Signal Surge Protectors are designed to protect sensitive communication and signal lines from transient voltage surges caused by lightning, switching events, and electrical disturbances. Signal lines entering or exiting a building are particularly vulnerable to induced surges, making properly applied surge protection critical at the point of entry or directly at equipment termination.

These surge protection devices are engineered to clamp excess transient voltage to levels that connected equipment can tolerate without disrupting normal signaling voltages. Transtector and Polyphaser solutions support a wide range of data and communication protocols, including Ethernet, Gigabit Ethernet, PoE, PoE++, USB, and wireless infrastructure. Multiple mounting options—such as panel, surface, rack, tower, hard-wired, pole-mounted, and outdoor enclosures—allow for flexible installation across network, industrial, and telecommunications environments.

Available product families include the Transtector ALPU PoE Series with SASD technology for compact RJ-45 protection, ALPU Fit and Lite models using gas tube and hybrid SASD designs for small cell and cellular networks, and the Thunderbolt Series combining high-power gas discharge tubes with TVSS protection for Ethernet and PoE bulkhead installations. Additional offerings such as the DPR, CPX, TSJ-USB, and MDPS Series provide bidirectional protection, carrier-grade performance, and support for outdoor NEMA 4X applications.
