The part of a typical Cutler-Hammer starter shown within section X is referred to as what?

In a typical Cutler-Hammer starter, the section referred to within the context of the question is known as the overload section. This part is crucial in protecting the motor from potential damage caused by overheating. The overload relay senses the current flowing to the motor and responds to any excessive current, which could indicate an overload condition.

When the current exceeds a predetermined limit for an extended period, the overload relay will trip, disconnecting the motor from the power supply to prevent overheating and potential failure. This protective feature is integral to motor operation and longevity, making the overload section a key component in a motor starter assembly.

Other components mentioned, such as auxiliary contacts and the contactor section, serve different functions. The auxiliary contacts are typically used for control purposes and to provide additional functionality, while the contactor section is involved in switching the power to the motor on and off. The power supply section would typically refer to the component supplying power to the operational parts of the starter but does not specifically relate to the overload protection function which is the primary consideration in this question.
