Newly designed protection element for overvoltages and overcurrents with three protection levels. The protective cascade combines a high discharge capacity with a short response time and ultra-fast current limiting, resulting in an outstanding protective effect.
NEW! Surge arrester and overcurrent protection in one module, certified for 5,000 amps (pulse class C2, tested at 10,000 V)
NEW! Clamping voltage only 10 V on the device side (after 1 µs)
NEW! Combination of three stages with a total of 24 protection and flashover paths
NEW! PE connection with very low contact resistance for uncut and low-impedance 2.5 mm² connection
NEW! Including two sets of terminals blue, grey and orange for three-pole connection of 1-Wire (5V, GND, DATA)
NEW! Now also available as SparPack or SuperSparPack with addition (one piece for five pieces or two pieces for 10 pieces)
This lightning protection module is designed for 1-Wire bus systems with the ElabNET Professional Busmaster or for protecting the 1-Wire channels of the Timberwolf servers, models 350Q, 950Q and 960Q.
For 1-Wire bus systems with other bus masters (e.g. Maxim DS9490R, Loxone 1-Wire Extension), we offer a separate protection module optimised for these bus masters that also contains a bus boost stage for increasing the range (this is already included in the PBM).
This 1-wire surge arrester of category C2 / Type 2 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 1-wire bus system and the equipotential bonding rail in case of direct and near lightning strikes as well as overvoltages from switching operations and discharges the partial lightning current into the earthing system. We recommend the combination with a surge arrester for power supply systems Type 1 and Type 2 and the use of several of these 1-Wire BlitzART modules in the 1-Wire system.
This module is designed for 1-Wire bus systems with the ElabNET Professional Busmaster or with the Timberwolf Server of the models 350Q, 950Q and 960Q.
Note: This module has three protective effects, which differ depending on the connection side. The power stage acts on the bus side of the module and can equalise or dissipate 5,000 amps. Both connection sides are connected via a three-pole overcurrent protection stage. The downstream fast fine stage initially acts on both connection sides at the onset of an overvoltage event; as soon as the overcurrent protection stage is activated, the current flow between the two sides is limited so that the voltage equalisation of the fine stage only has an effect on the device side (as long as the event lasts) and reduces the terminal voltage there again.
Note: For 1-Wire bus systems with other bus masters (e.g. Maxim DS9490R, Loxone 1-Wire Extension) we offer a protection module optimised for this purpose with included BusBoost and bandpass for optimum range.
Note for Loxone and other bus masters: For other 1-Wire bus masters such as Maxim DS9490R as well as Loxone 1-Wire Extension, we recommend the separately available 1-Wire BlitzART protection module, which includes a bandpass filter and a BusBoost stage for improved range on the 1-Wire bus in addition to a tighter current limit.
The capacitive load of the data line of the 1-Wire bus (DATA) by this surge arrester is a few picofarads, which corresponds to the capacitive loading of less than 1 m of bus line.
If the bus is longer (more than 50 m), we recommend installing another module in the middle of the bus. In this case, only connect the 1-wire bus to the bus side of this module. You can either connect a branch with 1-Wire devices to the device side or leave this connection unassigned.
With very long 1-Wire buses, install another module every 50 m.
Most important recommended additional measure: Have internal lightning protection (type 1 and type 2 arresters) for energy-technical networks installed on the low-voltage side.
Surge arrester type 2 for the Professional Busmaster (PBM) with three-stage protection system with disconnection of the current flow to the equipment side.
This surge arrester can discharge 5,000 amperes (8/20 µs, pulse category C2, fast rising edge). In addition, this protection system is equipped with the innovative ElabNET Current-Cut technology (self-resetting high-speed fuse 1µs). This enables additional protection even against low overvoltages (e.g. short circuit with 24 V due to wiring errors).
This BlitzART protection system is thus a combined protection system consisting of a very powerful type 2 surge arrester plus a very sensitive overcurrent protection (50 or 200 mA / 1 µs). The overcurrent protection switches off an overcurrent to the device side within one microsecond. The reset after the overcurrent event takes place automatically within one millisecond.
This short-circuits overvoltages, compensates potential differences and additionally separates remaining overcurrents. Due to this special combination, the achievable device protection is better compared to conventional protection systems without this third protection level.
Notes for use of other crimp terminals: Instead of the supplied crimping cable lug, you can also use other ones 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.
