SIEMENS SIPROTEC 7SJ6021-2EB20-1FA0/CC OVERCURRENT PROTECTION

Description

SIEMENS SIPROTEC 7SJ6021-2EB20-1FA0/CC OVERCURRENT PROTECTION
The SIPROTEC 7SJ602 is a numerical overcurrent relay which, in addition to its primary use in radial distribution networks and motor protection, can also be employed as backup for line, transformer and generator differential protection. The SIPROTEC 7SJ602 provides defi nite-time and inverse-time overcurrent protection along with overload and unbalanced-load (negativesequence) protection for a very comprehensive relay package. For applications with ground-current detection two versions are available: One version with four current transformer inputs for non-directional earth (ground) fault detection and a second version with three current inputs (2 phase, 1 earth/ground) and one voltage input for directional earth (ground) fault detection. The fl exible communication interfaces are open for modern communication architectures with control systems.
