Design principle
The Aino garbage machine protector is equipped with a jump bimetallic strip with a contact on the top and can pass an electric current. In case of overheating, the current passing through the Aino sheet will produce a heating effect, and the influence of motor heat will cause the temperature of the bimetal sheet to rise.
When the bimetal plate reaches the calibration setting point, the Aino protector will automatically disconnect the power supply, and the button will automatically lift under the force of the spring and get stuck between the two contacts, making the protector unable to automatically reset.
When the motor is cooled to the allowable operating temperature, manually press the button to restart the motor.
Why do we need to protect the motor?
Motor insulation overheating will lead to a decrease in dielectric strength and further damage or failure of the motor insulation. Use aino protector to provide protection against motor overheating in the following situations:
 long-term overload running
 locked-rotor - in mechanical/electrical start-up failure
 low line voltage
 high environmental temperature, lack of ventilation
Overall dimensions

Characteristic curve
Approximation - used only to select motor verification test samples

These curves are used only to provide guidance when selecting protectors for a particular application. Other factors should be considered when selecting a protector, such as the distance from the heat source and the method of installation. Final trip time depends on terminal configuration and installation conditions.
