The SIPROTEC 7SJ600 provides defi nite-time and inverse-time overcurrent protection along with overload and negativesequence protection for a very comprehensive relay package. In this way, equipment such as motors can be protected against asymmetric and excessive loading. Asymmetric short-circuits with currents that can be smaller than the largest possible load currents or phase interruptions are reliably detected.
