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.
In addition to the standard race distances, a race director could design a race that falls within a category: short, intermediate, long or ultra. A short-distance triathlon is anything that involves a swim of 0.2 to 0.6 miles, a bike portion of 5 to 18.6 miles and a run of 1 to 3.9 miles. Intermediate-distance triathlons consist of a 0.7- to 1.2-mile swim, an 18.7- to 31-mile bike ride and a 4- to 8-mile run. Long-distance triathlons have an athlete cover between 1.3 and 1.9 miles in the water, 31.1 to 62 miles on the bike and 8 to 18.6 miles running.
