Introduction

    In the world of electrical engineering, motor protection is paramount for ensuring the longevity and efficiency of electric motors. One fundamental device that plays a pivotal role in this protection scheme is the Current Overload Relay (COR). This crucial component autonomously monitors the electric current flowing to motors, providing an essential safety mechanism against potential overload and damage. In this article, we will explore the working principles, types, applications, and advantages of Current Overload Relays, emphasizing their importance in various industrial and commercial setups.
