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 are growing massively in popularity and as such there are now a multitude of different distance events to choose from, however the main categories are as follows: Super Sprint => Swim 400m / Bike 10km / Run 2.5km. Sprint => Swim 750m / Bike 20km / Run 5km. Olympic Distance => Swim 1500m / Bike 40km / Run 10km. Middle Distance (Half Ironman or 70.3) => Swim 1.2miles / Bike 56miles / Run 13.1miles.
