🛠Circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by overcurrent.
🛠Its basic function is to interrupt current flow to protect equipment and to prevent the risk of fire.
🛠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 low-current circuits or individual household appliances, to large switchgear designed to protect high voltage circuits feeding an entire city.
🛠The generic function of a circuit breaker or fuse, as an automatic means of removing power from a faulty system, is often abbreviated as OCPD (Over Current Protection Device).
