A 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 … See more An early form of circuit breaker was described by Thomas Edison in an 1879 patent application, although his commercial power distribution system used fuses. Its purpose was to protect lighting circuit … See more All circuit breaker systems have common features in their operation, but details vary substantially depending on the voltage class, current rating … See more Circuit breakers are rated both by the normal current that they are expected to carry, and the maximum short-circuit current that they can safely interrupt. This latter figure is the ampere interrupting capacity (AIC) of the breaker. Under short-circuit … See more Many classifications of circuit breakers can be made, based on their features such as voltage class, construction type, interrupting type, and structural features. Low-voltage See more Low-voltage miniature circuit breakers (MCB) use air alone to extinguish the arc. These circuit breakers contain so-called arc chutes, a stack of mutually insulated parallel metal plates that divide and cool the arc. By splitting the arc into smaller arcs the arc is … See more Circuit breakers are manufactured in standard sizes, using a system of preferred numbers to cover a range of ratings.
