Customizable setup
Parameterize for optimal relay fit. Integrate backup overcurrent protection for one winding or star point. Add optional impedance-based restricted earth-fault, negative-sequence and breaker failure protection.
Why SIPROTEC 7UT613?
The SIPROTEC 7UT613 differential protection relay provides fast, selective fault clearing for short-circuits. Protect short lines, busbars, electric machines like motors and generators, and transformers of all voltage levels. Short-circuits can threaten electrical infrastructure by causing damage and downtime. Our SIPROTEC 7UT613 relay offers rapid, precise fault detection and isolation. Parameterize the relay for optimal adaptation to minimize disruptions. Integrate backup overcurrent protection and optional restricted earth-fault, negative-sequence and breaker failure protection. Implement custom automation with integrated programmable logic (CFC) for more control. This product is currently being phased out. Contact your Siemens representative for details.
