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.n early form of circuit breaker was described by Thomas Edison in an 1879 patent application, although his commercial power distribution system used fuses.

One of the simplest forms of multisport, aquathlon consists of swimming and running. The official distances for the annual ITU Aquathlon World Championships are a 2.5km run, 1km swim, and 2.5km run. This can change if the water temperature is low, and in this instance the race becomes a 1km swim followed by a 5km run.
