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.
Since the shortest swim distance in a triathlon is likely 400â800 meters, and typically more, one needs to consider what training is required to sustain a good pace for the distance to be swum. 800 meters is no sprint.
The best swimmers among female Ironman triathletes complete the swimming portion of the event in 50 minutes to an hour. At the World Championship, the cutoff time for all competitors is two hours, 20 minutes. Any participant who fails to complete the 2.2-mile swim within that time is eliminated from the competition.
