... In an ideal case, the ammeter will not produce a voltage across itself. This is equivalent to stating that an ideal ammeter looks like a short circuit (i.e. the resistance across it is zero). This is because if it did develop a voltage, it would change the values of the currents and voltages across ...

Circuit breaker
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.
