Disconnects are used in it. When electricity is higher than normal as a case of short circuit. Thus cutting the fuse to prevent damage to appliances that
automatically switches the thermal. Fuse to form the previously mentioned lack of time need to be replaced every so inconvenient, so it automatically switches are designed to be used instead. The switches are shown in Figure 17.44 and are now at an electric current through the circuit breaker exceeds a certain size. Without any other part of the switch to the melting of a fuse. Automatic thermal switch that is most commonly used general households that use the principle of double sheet metal. Which will be studied further
