An overload relay, that is, an overload relay, is a commonly used device for the protection of electrical equipment. Its function is to provide overload protection to motors or other circuit loads to prevent overcurrent damage to equipment.

In industrial production, motors are one of the most commonly used loading devices. However, since the motor will inevitably experience load changes or other abnormal conditions during operation, overcurrent will occur when the motor load is too high. If such an engine runs for a long time, it may cause the engine or other equipment to burn. be damaged, which will cause production problems and cause huge economic losses.

To solve this problem, overload relays were created. It has an internal fixed value corresponding to the charging current. When the load current exceeds the set value, the overload relay will send a signal to the circuit to cut off the circuit to avoid damage to the load caused by overcurrent.

In short, the overload relay is a very useful electrical device. With its popular application, it can effectively improve the protection and reliability of electrical equipment and avoid accidental losses.
