The overload protection for a motor might be thermal overloads (sometimes called ) in the controller, electronic sensing overload devices, built-in thermal protection, or time-delay fuses.

Heaters.

Explanation:

An overload relay can be defined as an electromechanical device used for preventing overheating in electric motors. There are two (2) main types of overload relays and these includes;

I. Magnetic overloads.

II. Thermal overloads.

Basically, a thermal overload is typically used as an electromechanical protective device for motors. The thermal overloads are designed by manufacturers to effectively cut power off whenever a motor draws or consumes too much current over an extended period of time.

Hence, the overload protection for a motor might be thermal overloads (sometimes called heaters) in the controller, electronic sensing overload devices, built-in thermal protection, or time-delay fuses.
