Product Information:

Surge arrester for Power over Ethernet is a combination of coarse and fine protection of ethernet lines with Power over Ethernet (PoE). For the protection of ethernet line Cat 6 with PoE Mode A, B against surge voltages.

Features:

  • RJ45 sockets
  • Suitable for use on 10 Gbits/s Ethernet (Cat 6A) lines

Benefits: Simple installation. Universal plastic adapter for mounting on DIN rail and GND 2 holder

Standards: EN 61643-21 (Surge Protection Devices)

Application: Install at the entry into the building and close to protected equipment, at the boundary of LPZ0 and LPZ1 or higher.

More Informations:

Where low voltage, data and telecom lines enter and exit the building, they must also be included in the Lightning Protection System. These include:

  • Electromagnetic shielding
  • Telephone lines
  • Data communication lines
  • Instrumentation, control, signaling lines
  • Coaxial lines for CCTV, TV, & antenna cables

A surge or lightning protection device prevents damage to electrical and electronic equipment from transient over-voltage events by blocking or redirecting surge current to the ground instead of passing through the equipment.

By their nature, low voltage, data and telecom lines are not as robust as mains power cables and as such do not carry the same magnitude of lightning current. However, the size of that voltage/current is large in comparison to the system operating voltage and, as such, these lightning induced transients can still cause irreparable and expensive damage.

Since transients can be induced from the large electro-magnetic field created during a lightning strike, care needs to be taken over the routeing of such cables.

When selecting a data, telephone or low voltage protector, extra care must be taken to ensure that clamping performance of the SPD does not impede the data/signal transmission voltage.
