Newly designed protection element for overvoltages and overcurrents with THREE protection levels. The protection cascade combines a high discharge capacity with an extremely short response time and ultra-fast current limitation, resulting in an outstanding protection 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 12 protection and flashover paths
NEW! PE connection with very low contact resistance for uncut and low-impedance connection with 2.5 mm²
NEW! Including two sets of terminals green, grey and orange for three-pole connection of D+, D- and GND
NEW! now also available as a SparPack or SuperSparPack with addition (one piece for five pieces or two pieces for 10 pieces)
This lightning protection module is designed for all CAN-based bus systems such as Lox Link, Loxone Tree, CAN Bus (car, mobile homes).
Lightning and surge protection system certified according to DIN / IEC 61643, tested for use with CAN interfaces
Note: Loxone, Lox Link, Loxone Tree etc. are registered trademarks of Loxone Electronics GmbH, Kollerschlag, Austria.
The capacitive loading of the data lines of the CAN bus by this surge arrester is approx. 75 picofarads, which corresponds to the capacitive loading of less than 10 m of bus line.
The most important recommended additional measure is to have internal lightning protection (type 1 and type 2 arresters) for power networks installed on the low-voltage side.
Type 2 surge arrester for all CAN-based bus systems (especially Loxone Tree and Lox Link) with three-stage protection system with disconnection of the current flow to the device side.
This surge arrester can discharge 5,000 amps (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), which provides additional protection even against low overvoltages (e.g. short-circuit with 24 V due to wiring error).
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 (200 mA / 1 µs). Within one microsecond, the overcurrent protection switches off a possible damaging current to the side of the unit which could still occur due to the remaining protection level of the other two stages. The reset after the overcurrent event takes place automatically within one millisecond.
This short-circuits overvoltages, compensates for potential differences and additionally separates remaining overcurrents. Due to this special combination, the achievable device protection is at least ten times better than conventional protection systems without this third protection level.
This surge arrester for CAN based bus systems 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 CAN based 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 combining this module with a surge arrester for power networks Type 1 and Type 2 and using several of these CAN BlitzART modules in the respective CAN based bus systems (depending on the distance and number of devices on the bus).
This module is designed for use with all CAN-based bus systems (also Loxone Link and Loxone Tree).
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 compensate or discharge 5,000 amperes. Both connection sides are connected via a three-pole overcurrent protection stage. The downstream ultra-fast fine stage initially acts on both connection sides at the start of an overvoltage event; once the overcurrent protection stage is activated, the current flow between the two sides is limited, so that the voltage compensation of the fine stage only has an effect on the device side (as long as the event lasts) and drastically reduces the terminal voltage there again.
