When the bimetal thermal relay is used to protect the motor from overheating (overload), the protection current should be set according to the rated current of the motor. When the circuit current exceeds this value, the relay starts.
When the bimetal thermal relay is used to protect the motor from overheating (overload), the protection current should be set according to the rated current of the motor. When the circuit current exceeds this value, the relay starts.
Through the circuit current bimetal thermal relay exceeds the set value, because the temperature will not immediately rise to double sheet metal numerical action, which takes time to release some open top bending degree. The length of this time is directly related to the size of the current.
When the current of the circuit is less than or equal to the setting value, no action is required.
When the circuit current is maintained at the setting value of operation has reached a stable state after heat, if the current =1.2 settings, the action is within 20min; =1.5 circuit current setting value, the action is within 2min; >5 circuit current setting value, it will be within 5S around the time of action.
