Mechanical Fuse

A mechanical fuse, also known as a mechanical circuit breaker or a mechanical cut-out, is a safety device used to protect electrical circuits from overcurrent or short circuit conditions. It is designed to interrupt the flow of current when the current exceeds a predetermined threshold or when a fault occurs in the circuit.

Mechanical fuses consist of a metal wire or strip that melts or breaks when the current exceeds a certain level. When the current reaches this threshold, the wire or strip heats up and eventually melts or breaks, causing an open circuit and stopping the flow of electricity. This helps prevent damage to the electrical equipment and reduces the risk of fire or other hazards.

Mechanical fuses are commonly used in various applications, including residential, commercial, and industrial electrical systems. They are often found in electrical panels, control panels, motor circuits, and other areas where protection against overcurrent is necessary.

It is important to note that once a mechanical fuse has been triggered and the circuit is interrupted, the fuse needs to be replaced in order to restore the circuit's functionality. This is because the wire or strip that melted or broke cannot be repaired or reset.

Overall, mechanical fuses are an essential component in electrical systems to ensure the safety and protection of both the equipment and the users.
