High-speed tripping
Achieve high-speed tripping times to protect your system. The impedance setting range provides precise protection for even the shortest lines with very small settings.
Why SIPROTEC 7SA63?
The SIPROTEC 7SA63 is a distance protection relay designed for universal protection, control and automation across all voltage levels. It integrates seamlessly into the SIPROTEC 4 system to provide a robust solution for your electrical infrastructure.
Benefit from high-speed tripping times for rapid fault clearance, protecting your critical assets. The current transformer saturation detector prevents non-selective tripping, enhancing system reliability. Phase-segregated teleprotection further improves selectivity and availability for better system coordination and uptime.
Note: this product is being phased out.
