Overload relays are an essential component of many electrical systems. They protect motors and other equipment from damage caused by excessive currents and help ensure safe and reliable operation.

These relays work to sense the current flowing through a motor or other piece of equipment and turn off the power if it exceeds a predetermined level. This prevents the engine from overheating and causing damage or breakdowns.

The big advantage of overload relays is that they are very reliable and require minimal maintenance. They can operate for years without needing adjustment or replacement and can be easily replaced if they fail.
