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.
Still others change at each transition, especially in long races such as an Ironman, where seconds don't mean as much as comfort. One popular option are triathlon-specific shorts (tri shorts), shown at right. These shorts (some include tops to be racesuit-style) work well for all 3 stages of a triathlon. Tri shorts wick away moisture and dry quickly.
