Quick Summary
The Rittal DK 7979.723 Surge Voltage Protector Module provides Type 3 overvoltage protection for terminal equipment on enclosure frames. In modern automation, surges from switching, lightning, or grid disturbances threaten uptime and asset integrity. With CE compliance and IEC 61643-11 standardization, this module aligns with essential European safety and performance requirements. Its compact, assembly-friendly design supports fast commissioning and predictable protection outcomes for panel builders. The device is designed for mounting on enclosure frames and features 3-phase protection, 16 A rated current, and 11 kW rated power. By combining ready-to-connect wiring with sturdy aluminium housing and standardised connectors, it reduces on-site wiring errors and speeds up test commissioning. Manufacturers benefit from documented compliance (CE, IEC 61643-11) and a compact footprint tailored to tight panel spaces.

Product description
DK surge voltage protector module, for terminal unit protection (type 3) with alarm contact, for fastening to the enclosure frame, rated power: 11.0 kW, rated current: 16 A, 3~, connection type: CEE connector/coupling, connection cable / length: H05VV F5G2.5 / 1 m, extruded aluminium section, anodised, RAL 9005, incl. assembly parts, DK surge voltage protector module
Fully wired, ready-to-connect protection reduces installation time and wiring errors, cutting commissioning costs and minimizing field faults. This accelerates time-to-production for machine builders and panel shops, especially in high-mix, low-volume environments where every minute counts. The rugged aluminium extrusion, anodised finish, and RAL 9005 colour ensure lasting performance in harsh factory conditions, while maintaining a clean, standardized panel appearance. With a 3-phase, 16 A / 11 kW specification and a CEE connector, it integrates smoothly into existing control architectures, lowering wiring complexity and improving reliability. The 1 m input and output cables (H05VV-F 3G2.5) simplify routing in compact frames and support rework or expansion without rewiring; assembly parts are included for quick installation. The module is designed to work alongside other Type 1 or Type 2 protectors to form a complete protection chain, meeting industry practice for layered surge defense. The compact dimensions (Width 44 mm, Height 75 mm, Length 250 mm) enable deployment in space-constrained enclosures without sacrificing performance.

FAQs
Yes. The DK 7979.723 is designed for mounting on standard enclosure frames and uses a compact aluminium profile with mounting hardware included. Its dimensions and mounting provisions align with typical DIN-rail and frame applications, enabling straightforward integration into existing control cabinets.
Key specs include a 3-phase design with a rated current of 16 A and rated power of 11 kW. It uses a CEE connector for robust, panel-friendly wiring and includes 1 m input and 1 m output cables (H05VV-F 3G2.5). This places it as a final-stage Type 3 surge protector suitable for protecting terminal equipment.
Type 3 protection is ideal for protecting sensitive terminal equipment in industrial automation, machine control cabinets, and process automation where earlier protection stages (Type 1/Type 2) exist upstream. It’s commonly used in manufacturing, packaging, and water/energy sectors where uptime and equipment life are critical.
The DK 7979.723 is designed to comply with IEC 61643-11 and carries CE marking under the Low Voltage Directive 2014/35/EU. This combination supports safe integration into EU-based control systems and helps ensure regulatory alignment for panel builders.
Being fully wired and ready-to-connect, it minimizes field wiring and debugging time, reducing commissioning costs. The robust aluminium housing and standard connectors improve reliability, lowering maintenance interventions. Assembly parts included further streamline procurement and on-site installation, delivering measurable total cost of ownership benefits.
