Working principle

With a stop button
With manual and automatic reset buttons
Electrically separable 1NO+1NC contact

The bimetal elements of the thermal relay are connected in series in the main circuit. When the line current increases, the bimetallic element is heated and bent to a certain extent to push the sliding plate, and the normally closed contact is separated from the push rod by compensating the bimetallic element. Ensure that the motor is out of phase and overload is effectively protected
