What is the purpose of the mechanical mechanism paired with the eutectic alloy?

The purpose of the mechanical mechanism paired with the eutectic alloy is to activate a tripping device during an overload condition. In motor protection, the eutectic alloy is designed to respond to excessive heat generated by overloads. When the temperature rises to a certain point, the eutectic alloy will melt, allowing the mechanical mechanism to trigger a switch or trip the circuit, thereby disconnecting the motor from the power supply and preventing damage. This function is essential in safeguarding motors against overheating, ensuring that they operate within safe limits and maintain longevity.

In the context of motor protection, the primary goal is to prevent damage due to overloads, making this mechanism vital for the safe operation of electric motors. The other options do not accurately reflect the role of the eutectic alloy and mechanical mechanism combination in protecting the motor.
