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.
After one mile, as your next milestone, Iâd suggest 5000 meters (5500 yards) or 3.1 miles â the equivalent of runningâs half marathon. It will take 90 minutes to two hours for most fitness swimmers or triathletes to swim this distance in open water. Beyond that the swimming equivalent of a 26.2-mile running marathon would be a 10,000-meter (6.2 miles) swim. U. S. Masters Swimming offers both open water championships and pool postal swims at those distances.
