The equipment, located in the upper part of the fuse switches, includes a LED indicator that shows the status of the fuse, indicating green when all the fuses are in operation, red when there is a blown fuse or off when there are no fuses inside.

Within the range of fuse monitoring solutions, there are electronic monitoring, electromechanical monitoring and the Modbus version that allows this information to be transmitted in real time to the customer’s central platform through a RTU.
