Two identical operation stages allowing the clos-
ing conditions for two separate circuit breakers
to be checked at the same time
Synchro-check function available in both opera-
tion stages for energized networks
Voltage-check function available in both opera-
tion stages for energized and non-energized net-
works
Two different operation modes in both stages:
continuous mode operation and command mode
operation
SPCU 3D45
Synchro-check
relay module
Alarm from the command mode operation if
the closing command attempt fails
Numerical display of setting values, measured
values and values recorded on relay operation
Setting values may be manually set by using
push-buttons on the front panel or via the se-
rial communication interface with a personal
computer
Continuous self-supervision of both hardware
and software of the relay with built-in auto-diag-
nosis
