Understanding the Importance of Motor Overload Relay in Electrical Systems

In the world of industrial and commercial electrical systems, ensuring the safety and longevity of motors is a key concern. One of the critical components designed to safeguard motors from damage due to excessive current is the Motor Overload Relay. This small yet crucial device plays a significant role in preventing electrical motor failures, which can lead to costly downtime and potential equipment damage. In this article, we will explore the function, working principle, benefits, and applications of the Motor Overload Relay. What is a Motor Overload Relay? A Motor Overload Relay (MOR) is an electrical protective device that monitors the current flowing through a motor to prevent it from running under overload conditions. It is commonly used in conjunction with motor starters in electrical circuits to ensure the motor does not overheat or suffer from damage when it experiences prolonged overload conditions.
