What is the primary function of the motor overload switch?

The primary function of the motor overload switch is to prevent fires and protect the motor from damage. This safety device monitors the current flowing to the motor and will interrupt power if it detects excessive current that could result from conditions such as jams, mechanical failures, or overheating. By cutting off power in these situations, the overload switch helps to prevent damage to the motor and the risk of fire, ensuring safe and reliable operation of the equipment.

While increasing motor efficiency, enhancing power output, and regulating fuel supply are important aspects of motor and system functionality, they do not directly relate to the protective role that the motor overload switch plays in safeguarding both the motor and the surrounding environment.
