Suitable for protection of Timberwolf Server, Loxone Miniserver, KNX power supply, KNX line amplifier, KNX line coupler, KNX area coupler, KNX USB interface, KNXnet/IP Tunneling IP Interface and KNXnet/IP Router and all KNX devices. According to DIN / IEC 61643 zertified lightning and surge protection system, tested for use in all KNX-TP bus systems.
Newly designed surge protection element with two protection levels. The protective cascade combines a high discharge capacity with a particularly short response time, resulting in a low protective voltage. Compared to conventional KNX surge arresters, up to 20 times better protection is achieved for the connected KNX devices.
NEW! Very low protection level of only 220V / 370 V
NEW! Fast response from 40 ps (approx. 1,000 times faster than conventional single-stage arresters)
NEW! Combination of two stages with a total of five protective and flashover paths for optimum discharge
NEW! PE connection with very low contact resistance for uncut and low-impedance connection with 2.5 mm² to lightning current equipotential bonding
NEW! Including two terminals each rt/sw and ge/ws for use with KNX-TP or KNX auxiliary voltage
In the video we explain this surge protection for KNX-TP and KNX auxiliary voltage. The chapters in the video are:

This KNX surge arrester of category C2 (comparable to Type 3) according to IEC 61643-21 is intended for installation in distribution cabinets and junction boxes in dry residential and business premises, control cabinets in industry and automation systems. It serves as a surge arrester between electrical conductors of the KNX bus system and the equipotential bonding rail in the event of direct and close lightning strikes and discharges the partial lightning current into the earthing system.We recommend the combination with a surge arrester for power supply networks Type 1 and Type 2 as well as the use of several of these KNX BlitzART modules in the KNX system.
This module has no functional direction, the connected bus lines and devices are equally protected on both sides of the surge protection module. When the bus signal is passed through the module, the reaction is slightly faster; we recommend connecting the more sensitive KNX devices on the side with the shorter bus line.
The capacitive load of the KNX bus by this surge arrester is 1 nF, which corresponds approximately to the capacitive load of 10 m bus line.
Surge arrester C2 for the KNX bus system with two-stage arrester system for optimum device protection.
This surge arrester has been certified for 1,000 amperes (8/20 µs) in pulse category C2, fast rising edge.
The two-stage BlitzART protection system is a cascaded protection consisting of a powerful and a fast surge arrester. This cascading improves the achievable equipment protection by a factor of about twenty compared to conventional single-stage surge arresters.
Notes on using other crimp terminals: Instead of the supplied crimping cable lug, you can also use others if you want to connect with a larger cross-section or use a solid conductor. Pay attention to the hole for M3. Crimping cable lugs with 4 and 6 mm² are available in the trade for this purpose. Please make sure to use the correct crimping tool for the respective crimping cable lug.
