Introduction

    Electric motors are essential components in industrial and commercial machinery, providing power for everything from conveyors to HVAC systems. However, motors are susceptible to damage if subjected to excessive current or poor operational conditions, which can lead to overheating, reduced efficiency, or even complete failure. To prevent these issues, one of the most critical safety devices used in motor control circuits is the Motor Overload Relay (MOR). This article will explore the importance of Motor Overload Relays, how they work, their different types, and why they are vital in ensuring the longevity and performance of electric motors.
