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.
Distance variations for a sprint triathlon exist because of course constraints or race promoters' preferences. The swim in some sprint-distance triathlons may be as short as 500 meters. The bike portion can range from 12 to 16 miles, while the run can range from a flat 3 miles to 3 1/2 or farther. Super-sprint triathlons are geared toward newbies who want to try out the sport for the first time. These races may consist of a 250- to 500-meter swim, a 7- to 10-mile ride and a 1- to 2-mile run.
