A overload relay is an electrical equipment used to store electrical equipment. It is often used in high-end electrical and industrial applications, such as motors. It can detect changes in motor current and activate a circuit breaker or other safety device when the current exceeds the protected value to prevent damage to equipment due to overload.

The benefits of using a overload relay are obvious. It can prevent equipment damage caused by overload and ensure the stability and reliability of the production process. Without overload relays, motors and other electrical equipment can overheat and damage from continuous operation, ultimately leading to equipment downtime and delayed repairs.

Therefore, overload relay is a very important electrical device, which not only protects the equipment and improves productivity, but also ensures the safety of the workers.
