Ordering Information and Accessories
A.1 Ordering Information 7SJ80
Functions
Basic design 5)
+ direction determination for phase
+ voltage protection
+ frequency protection
+ synchrocheck
1) depending on the ground current input at position 7, the function works either as ground fault protection (sensitive
input) or as ground short circuit protection (normal Ie input)
only with sensitive input, Position 7=2
2)
3) only deliverable with position 6 = 1, 2 or 7
4) only deliverable with position 6 = 3, 4 (3 x V) or 8
5) only deliverable with position 6 = 3, 4 (3 x V) or 8 and position 16 = 0 or 1
Automatic reclosing function 79AR / Fault locator 21FL
1) only deliverable with position 6 = 1, 2 or 7
