Combined arresters for data networks and MCR-technology represent a critical line of defense in modern industrial and commercial electrical installations. These devices integrate overvoltage and surge protection specifically designed for sensitive data transmission lines, control circuits, and measurement systems. Typically featuring multi-stage protection circuits with gas discharge tubes, transient voltage suppression diodes, and varistors, they ensure rapid clamping of transient overvoltages while maintaining signal integrity. Key technical parameters include nominal discharge current (In), voltage protection level (Up), and frequency bandwidth compatibility. These arresters are available in various configurations such as single-pair, multi-pair, and coaxial variants, with mounting options for DIN rails or direct panel installation. They are essential for safeguarding Ethernet, Profibus, RS-485, and other industrial communication protocols against lightning-induced surges and switching transients.
These devices find extensive application in industrial automation networks, process control systems, building management systems, and telecommunications infrastructure. They are commonly installed in control cabinets, distribution boards, and field junction boxes where data cables enter or exit protected zones. Typical sectors include manufacturing plants, power generation facilities, water treatment plants, oil and gas refineries, and transportation systems. Combined arresters are also critical in renewable energy installations, such as solar farms and wind turbines, where long cable runs increase exposure to induced surges. Their use ensures compliance with standards like IEC 61643-21 and EN 61643-11 for surge protection in low-voltage data networks.
Within this category, key subcategories include combined arresters for Ethernet networks (e.g., models with RJ45 connectors), for serial interfaces (RS-232, RS-485), and for fieldbus systems (Profibus, Foundation Fieldbus). Specific article codes often follow a pattern like "DG S 1" or "DG M 2" where letters indicate the series and numbers denote the number of protected pairs or signal lines. For example, the "DG S 1" series typically protects one signal pair, while "DG M 2" covers two pairs. Other common codes include "CN-UB/E" for coaxial protection and "PT 2X1-24DC-ST" for modular pluggable arresters. These codes are usually structured with prefixes indicating the product family, followed by specifications for voltage rating, number of conductors, and connection type.
