标题: Understanding Motor Overload Relay: Protection and Benefits for Electric Motors

Electric motors are crucial components in various industries, powering machines, pumps, fans, and countless other devices. While these motors are built to handle high workloads, they are not invincible, and prolonged exposure to overloads can lead to overheating, reduced efficiency, and ultimately motor failure. This is where a Motor Overload Relay (MOR) plays a vital role. In this article, we will delve into the importance of the Motor Overload Relay, how it works, and the benefits it brings to electric motor protection. What is a Motor Overload Relay? A Motor Overload Relay (MOR) is a protective device used to safeguard electric motors from damage caused by prolonged overloading. When an electric motor runs at a current that exceeds its rated value for an extended period, it can overheat and potentially burn out. The overload relay is designed to detect such overload conditions and disconnect the motor from the power supply before it is damaged.
