Understanding Overload Relay: Protection for Your Electric Motor
An Overload Relay is a critical component used in the protection of electric motors, ensuring their longevity and preventing damage due to overcurrent or excessive load. These relays are often used in combination with motor starters to safeguard motors from operating under unsafe conditions. When an electric motor is subjected to a higher load than it can handle, the overload relay detects this and disconnects the motor from the power supply, thereby preventing overheating and permanent damage.
What is an Overload Relay?
An overload relay is a type of protective relay designed to monitor the current flowing through an electric motor. Its primary purpose is to prevent the motor from drawing excessive current, which could lead to overheating and eventually damage the motor windings. It acts as a safety device by breaking the circuit when the current exceeds a certain threshold, ensuring the motor operates within its safe limits. Overload relays are commonly used in industrial and residential applications, where motors play a vital role in driving machines and equipment.
