ANSWER

fuse

EXPLANATION

A fuse is a piece of metal (or sometimes a very thin wire) whose surface area is much smaller than the wires of the circuit. When a high amount of current starts circulating this device disspates greater power than the wires and it melts before the wires do, opening the circuit and preventing the wires and other components from burning.
