The ZB32/XTOB…CC1 relay can also be operated
individually in combination with a separate mounting.
Table 2: Separate mounting
In the event of an overload trip, auxiliary contacts 95-96 and
97-98 switch and interrupt the control circuit of the relevant
contactor. In this way, they indirectly disconnect the power
flow of the monitored motor.
