Why SIPROTEC 7SD610?
The SIPROTEC 7SD610 relay provides differential protection for lines, cables and transformers across all voltage levels and network types.
The SIPROTEC 7SD610 protects electrical systems from diverse faults using high-speed, phase-selective short circuit measurement for rapid, precise clearance of single-phase and three-phase faults. Provide reliable protection for complex applications like series and parallel compensated lines.
Enhance system reliability with two independent differential stages: sensitive high resistance fault measurement and fast high current fault clearing. Digital data communication via fiberoptic cables or pilot wires extends protection over long distances.
This product is currently being phased out. Contact your Siemens representative for details.
