Voltage protection relay SIPROTEC 7SS85

three-phasepanel-mountIEC

SIPROTEC 7SS85 busbar protection is a selective, safe and fast protection against busbar short circuits in a large variety of busbar configurations. Why SIPROTEC 7SS85? The SIPROTEC 7SS85 busbar protection delivers selective, safe and fast protection against busbar short circuits in medium, high, and very high voltage systems. Built on the flexible, scalable and user-friendly SIPROTEC 5 platform, it sets a new standard for busbar protection. This solution integrates centralized, decentralized or hybrid busbar protection architectures while remaining fully IEC 61850 compatible and interoperable. The same device can collect process information directly and from distributed bay units, offering versatile and cost-efficient protection for distribution, industrial or infrastructure grids. Key benefits Protect your busbar quickly and selectively The SIPROTEC 7SS85 applies phase-selective measurement, disconnector-independent check zones and rapid tripping to minimize system damage and maintain network stability. Adapt to your operational needs Configure all functions with DIGSI 5 and select bay units that match your hardware and protection requirements. Optional redundant communication improves system reliability. Integrate with confidence Full IEC 61850 interoperability and process bus support allow seamless integration with existing SIPROTEC 5 devices, merging units and multivendor systems.
