What kind of device typically includes overload protection?

An electric motor typically includes overload protection because motors are at risk of damage from excessive current due to issues such as mechanical stalling or excessive load conditions. The overload protection mechanism is designed to detect conditions that might cause the motor to draw more current than it is rated for, preventing overheating and potential failure.

This protection can come in the form of thermal overload relays or circuit breakers that disconnect the motor from the power supply when it detects an overload condition, ensuring the longevity and integrity of the motor. In contrast, while devices like light bulbs, switches, and transformers have their own protective features, they do not generally require dedicated overload protection like an electric motor does due to their different operational characteristics and risks.
