The overload protection cut-out setting can be higher than the rated motor current to prevent
it from being triggered by voltage fluctuations, temperature influences or component toleran‐
ces.
1. Read the rated motor current from the nameplate and calculate the correct protection setting.
2. Check the motor overload protection switch setting.
3. Adjust the protection setting, if necessary.
The machine is shut down by the motor overload protection switch?
➤ Allow the motor to cool down.
➤ Switch the machine on again.
7.4.2 Resetting the motor overload protection switch for single-phase motors
Single phase motors are fitted with a thermal overload protection switch that is set to a fixed value.
It ensures shutdown of the machine at levels of current above the value set on the motor overload
protection switch.
➤ Have the machine checked if the motor overload protection switch trips out frequently at
short intervals.
