Applications Of Siemens 7SK80 Numerical Relay

Motor protection 

Designed for protecting induction-type asynchronous motors, the SIPROTEC 7SK80 device offers specialized motor protection features.

Transformer protection 

The SIPROTEC 7SK80 device offers all the fallback protection features needed for transformer differential protection. The inrush suppression successfully avoids unnecessary journeys that may be brought on by inrush currents.
