Description of device

Overload protection with current transformer-oper-
ated overload relay
The ZB65-.../XTOB...DC1 and ZB150-.../XTOB...GC1 over-
load relays are 3 pole electromechanical overload relays and
are equipped with bimetallic releases. They are suitable both
for AC and for DC operation.
The ZB65-.../XTOB...DC1 and ZB150-.../XTOB...GC1 over-
load relays can be mounted directly onto DIL contactor
relays.

The ZB65/XTOB...DC1 relays can also be operated indivi-
dually in combination with a separate mounting.
The ZB150-...KK/XTOB...GC1S relays are designed for
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.
