Which electrical device blows up when there is overloading in a circuit?

Answer. When an overload occurs, a fuse or circuit breaker prevents this by "blowing," or severing the circuit. Inside the fuse box, fuses are screwed into threaded sockets. The fuses have a thin metal strip inside that melts if the current (or amperage) running through the circuit exceeds the fuse's rated capacity.
