Integrated communication and commands
Control circuit breakers and isolators with integrated command functions. Employ digital relay-to-relay communication for robust data exchange.
Why SIPROTEC 7SA61?
The SIPROTEC 7SA61 distance protection relay provides universal protection, control and automation for electrical systems. Implement this flexible relay across all voltage levels to secure your infrastructure.
Deliver reliable and selective protection for your electrical network. This relay prevents non-selective tripping with its current transformer saturation detector for system stability. Achieve high-speed fault clearance and precise protection for even short lines.
High-speed tripping times that enhance system stability and reduce downtime. Digital relay-to-relay communication improves selectivity and availability for optimized fault isolation.
This product is currently being phased out. Contact your Siemens representative for details.
