Parameter Value Description
disk emulation
Select this setting if the device is coordinated with electromechanical
devices or other devices which perform a dropout after a disk emulation.
instantaneous
Select this setting if the dropout is not to be performed after disk emulation
and an instantaneous dropout is desired instead.
Parameter:
1-pole operate allowed
•
Default setting
(_:691:11) 1-pole operate allowed
=
no
The parameter must be set for the specific application.
Parameter Value Description
no
The stage always operates 3-pole.
yes
The stage operates phase-selectively. However, tripping by the device
(generated in the trip logic of the Circuit-breaker function group) is always
3-pole because the device does not support phase-selective tripping.
