Circuit breaker is closed in 3 poles (for the control functionality) automatically from the 1-
pole information.

Execute the routing of the Position 3-pole signal as O_ (open). In the following figure, routing is
executed as OH, in which H stands for active with voltage.

Depending on the design of the circuit breaker, other auxiliary contacts can be available in the system. In this
case, the device allows all routing options and acquires the necessary information automatically. Since all
routing options are possible on the device, there is no need for auxiliary contacts to be connected in series.
The device can also function without the analysis from the circuit-breaker auxiliary contacts, that is, routing of
the auxiliary contacts is not absolutely necessary.
Parameter: Output Time

Default setting (_:101) Output time = 0.10 s
The Output time parameter acts on the signals for tripping, opening, and closing of the circuit breaker.
