4 Intended use
Motor protection switch for protecting the
single-phase AC fans. With main contactor and
control fuse. For fans with integrated thermal
switch and fitted TB thermal contacts. For indoor,
surface-mounted wall installation.
The motor protection switch is only intended for
domestic use and similar purposes.
5 Function
The motor protection switch protects the fan mo-
tor against over-voltage/overheating. If the permit-
ted temperature in the motor winding (control cir-
cuit – TB thermal contact) is exceeded, the main
contactor drops out and disconnects the motor
from the mains. After the motor winding has
cooled down, which can take up to 30 minutes
depending on the fan, a restart interlock in the
unit prevents the automatic switch-on of the mo-
tor.
To switch back on → Fault rectification [} 7].
6 Safety instructions
CAUTION Risk of injury due to fan start-
ing up after a power failure or when working
in the fan's danger zone.
The motor protection switch reacts to overheat-
ing, e.g., in the event of over-voltage. If cooled
after a power failure, the fan motor can start up
automatically. Do not reach into the area
around the fan impeller and do not stick in
objects near the impeller.
Generally disconnect the fan from the power sup-
ply when working in the fan's danger zone (dur-
ing installation, cleaning, maintenance and repair
work).
DANGER Risk of explosion if explosive
gases/dusts are ignited.
Never use unit in an explosive atmosphere.
