12 V on the bus-side connections in the event of incorrect wiring).
Self-resetting, fast-acting overcurrent protection device, thus protection even against low overvoltages (e.g. Arresters for overvoltages due to switching operations in low, medium and high voltage networks (switching overvoltage). Arresters for overvoltages due to remote lightning strikes (e.g. Arrester for overvoltages from galvanic, inductive and capacitive coupling due to close lightning strike (atmospheric overvoltage). Surge protection device as part of the internal lightning protection for RS-485 / RS-422 based bus systems. This module is designed for all RS-485 / RS-422 bus systems without restrictions. It serves as a surge arrester between electrical conductors of the RS-485 / RS-422 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 networks Type 1 and Type 2 and the use of several of these RS-485 / RS-422 BlitzART modules in the system. This RS-485 / RS-422 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. Intended use / scope of application / intended use: This surge arrester for information technology systems has been certified according to IEC 601 + A1:2009 test C2 for "fast rising edge" and corresponds to arrester type 2. Due to the combination of short response time, low protection level and fast current limitation, this protective element minimises the load on the protected devices in the RS-485 / RS-422 based bus system as well as on the insulation on the device side to practically zero. Protection level on the bus side between D- against GND: 605 V (for pulse class C2, 10,000 V (1.2/50 us) / 5,000 A (8/20 us) - on the unit side, however, only for 1 µs, afterwards terminal voltage 10 V. Protection level on the bus side between D+ against GND: < 616 V (for pulse class C2, 10,000 V (1.2/50 us) / 5,000 A (8/20 us) - on the unit side, however, only for 1 µs, thereafter terminal voltage 10 V. Low-impedance PE connection for uncut connection for lightning current equipotential bonding with 2.5 mm². High discharge capacity and low dynamic resistance due to parallel-acting protective gaps.
