Overload relay is a protection device used in power equipment. It senses the size of the load current, and when the current exceeds the preset range, it will immediately cut off the circuit to prevent overloading of the equipment, causing a fire or damaging electrical equipment. This device not only protects equipment but also keeps people safe.

In the industrial production process, the load of the equipment usually fluctuates, so an overload relay device must be used to protect the equipment and prevent the equipment from being damaged after working for too long under high load conditions. The overload relay can monitor the current status of the device, adjust the load at any time and ensure that the device works according to the appropriate load.

In short, overload relay is a key power equipment protection device that can ensure people's safety and the stable operation of equipment.
