Which device is used for coordination and protects the customer's system?

The electronic fuse is a device designed to provide both overcurrent protection and coordination for an electrical system. It operates by monitoring the current flowing through the circuit and will disconnect the load when it exceeds a predetermined threshold, thus protecting the customer's system from damage due to overcurrent events such as short circuits or overloads.

Electronic fuses are advanced over traditional fuses because they can offer more precise control and faster response to abnormal conditions. They can also integrate with smart grid technologies, facilitating better communication and coordination within the system. This makes them highly effective in safeguarding customer equipment and maintaining operational integrity.

Although other devices like circuit breakers also provide protection against overcurrent, electronic fuses can be more effective in providing tailored protection and rapid response, making them advantageous for modern electrical systems that require a high level of coordination and safety. Voltage stabilizers and transformers do not primarily serve the purpose of protecting the system from overcurrent; rather, they serve different functions in the provision and regulation of electrical power.
