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.
Triathlons range in all sorts of distances. Sprints typically have (400-800 yard swim, 10-20 mile bike, and 2-5 mile runs). Then you have international distance: (1.5 km swim, 40km bike, and 10k run). So you have to know how far you will need to cover in a race to safely know how long you should train for that event.
