Surge protective devices for information technology

Surge protection for information technology and telecommunications

IT interfaces are particularly sensitive to overvoltages. Ideally, high transmission rates should not be impaired by the protective circuit. Powerful and fast-acting components provide a good level of protection with minimal attenuation. Overvoltages are safely limited. The bandwidth remains virtually unaffected.

DATATRAB DT from Phoenix Contact: protection for many IT applications

DATATRAB product family

DATATRAB DT – universal protection for information technology

The DATATRAB DT product family from Phoenix Contact provides protection for many applications:

  • High-speed networks up to 10 Gigabit Ethernet
  • Networks with RS-485 interface
  • Analog and digital interfaces for telecommunications, including DSL

All surge protective devices are system-compliant and have the appropriate connection technology.

The DT-LAN-CAT6+ version supports various data protocols at very high transmission speeds: such as Ethernet, Power over Ethernet (PoE), ISDN, token ring, and DS1.

DATATRAB can either be used as an adapter or as a DIN rail module.

TERMITRAB surge protective devices for VDSL applications

TERMITRAB complete for VDSL applications

TERMITRAB complete for telecommunications interfaces

With an overall width of just 6 mm, TERMITRAB complete provides narrow and reliable protection for telecommunications interfaces in the form of the TTC‑6‑1x2‑TELE… solution. The protective circuit is optimized for VDSL applications. Even at high data rates of up to 250 Mbps, the compact surge protection solution reliably protects against transients, without influencing the wanted signal.

The protective devices for telecommunications interfaces are available with Push-in as well as screw connection technology.

PLUGTRAB PT-IQ also for data interfaces

PLUGTRAB PT-IQ intelligent surge protection

PLUGTRAB PT-IQ for data interfaces

PLUGTRAB PT-IQ intelligent surge protection now also reliably protects your data cables against overvoltages. The protective circuit is specifically tailored to HF applications. All voltage-limiting components in the protective circuit are constantly monitored.

Your advantage: pre-existing damage caused by frequent overvoltages is detected and indicated. Thanks to the multi-stage status indicator, you can always determine the status of the protective devices:

  • Red = replacement required
  • Yellow = replacement recommended
  • Green = protective device OK

Using the controller, you can implement group remote signaling for all connected protective devices. You can choose between conventional screw connection and convenient Push-in connection technology.

Surge protection for information technology


Typical areas of application

Protective devices for information technology are split into two areas:

  • Data interfaces
  • Telecommunications applications

Data technology works with very low voltages and high transmission speeds. In contrast, due to the cable infrastructure, telecommunications systems use lower data transmission speeds in conjunction with higher voltages.
