Overload relay and contactor wiring connection YouTube
An overload relay is a device that protects an electric motor against overloads and phase failure. It senses the overloading of the motor and interrupts the power flow to the motor, thus protecting it from overheating and winding damages. Apart from overloads, it can also protect the motor from phase loss/ failures and phase imbalance.

Electrical Standards Overload relay working principle and features of thermal motor overload
Overload relays are devices that protect electric motors from overloads and phase failure. When the motor is overloaded, it detects this and terminates the power flow, preventing the motor from overheating and winding damage. It can also protect the motor from phase loss/failures and phase imbalance, in addition to overloads.
