An Overload Relay is a safety device used to protect electrical motors and other equipment from the detrimental effects of overloading. It is typically used in conjunction with motor starters to monitor the current flowing through the circuit. When the current exceeds a predefined limit, the overload relay activates and disconnects the power supply to the motor, preventing it from overheating and sustaining damage.

    Overload relays are particularly important in industrial and commercial applications where motors and other machinery are in constant operation. Without such protective devices, machines can quickly overheat, causing costly repairs, downtime, or even complete equipment failure.
