4.6 Overload Protection

Take note of the relevant circuit diagram for motors with thermally activated winding protection (see chapter 4.4 Cage
Clamp Connection Diagram).
Avoid automatic resetting after the winding has cooled.
The output of the motors is normally adequately rated. The rated current does not represent a measure of gear unit
utilisation in these cases and cannot be used as overload protection for the gear unit. In some cases, the way in which the
driven machine is loaded can exclude any overloading as a matter of course. In other cases, it is necessary to protect the
gear unit by mechanical means (e.g. slip clutch, sliding hub etc.). This depends on the maximum permissible limit torque
M in continuous running duty specified on the nameplate.
