Surge Arrester

Patch cable with built-in surge protection Cat. 6 according to ISO/IEC 11801 CAT 6A in the channel according to ANSI/TIA/EIA-568 Power over Ethernet (PoE+ according to IEEE 802.3at) Easy to retrofit


Designed as a patch cable, DEHNpatch can be easily installed in new installations or retrofitted into existing installations. DEHNpatch is installed between the patch panel and the active component (a switch for example) instead of the conventional patch cable. The snap-in mechanism of the supporting foot allows the device to be safely earthed via the DIN rail. For single application, DEHNpatch comes with a piece of DIN rail and a fixing device. A mounting set is also available as accessory for multiple application in 19“ distribution boards. Fulfilling the requirements of Category 6, DEHNpatch can be universally used for all data services up to nominal voltages of 57 V. Both existing applications in offices and industry such as Gigabit Ethernet, ATM or ISDN as well as future services such as Voice over IP and Power over Ethernet can be protected. Due to its fully shielded design, DEHNpatch can be used in shielded and unshielded networks. Its width is similar to that of an RJ45 socket, allowing up to 24 devices to be installed next to one another in one series and to be integrated into a 19" rack. DEHNpatch is available with a total patch cable length of 3 m and 5 m (other lengths can be provided available on request).
