– is protected against overheating by thermal overload releases or a motor
overheating protection unit.
When using thermal overload releases, the motor has to be protected as fol-
lows:
– during operation by a release set to the rated current and
– during start-up by a second release set to 1.8–2 times the rated current.
The release set to the rated current must be bridged during start-up.
Overheating protection is only possible if PTC thermistors are built into the mo-
tor winding.
Note:
•
The temperature feelers must be connected to a commercial tripping device.
•
External voltage higher than 2.5 volts must not be applied to the connection
terminals of the temperature feelers.
•
When testing for continuity, use an ohmmeter and not a test lamp.

When the direction of rotation is incor-
rect the motor connections must be
reversed by an authorised specialist.
