Power supply.
The rated CT currents applied to the
SIPROTEC 7SJ602 can be 1 A or 5 A. This
is selectable via a jumper inside the relay.
Two different housings are available. The
ush-mounting version has terminals
accessible from the rear. The surfacemounting version has terminals accessible
from the front. Retrotting of a communication module, or replacement of an
existing communication module with a
new one are both possible.

Cold load pickup
By means of a binary input which can be wired from a manual
close contact, it is possible to switch the overcurrent pickup
settings to less sensitive settings for a programmable duration
of time. After the set time has expired, the pickup settings automatically return to their original setting. This can compensate for
initial inrush when energizing a circuit without compromising
the sensitivity of the overcurrent elements during steady state
conditions.
One or two binary inputs can be used for trip circuit monitoring.
Control
The relay permits circuit-breakers to be opened and closed
without command feedback. The circuit-breaker/disconnector
may be controlled by DIGSI, or by the integrated HMI, or by the
LSA/SCADA equipment connected to the interface.
