Short circuits and overloads put different demands on circuit breakers, and it isrnimportant that engineers know how to protect their designs against both dangers.rnThe correct choice of circuit protection will enhance equipment reliability,rnreduce cost of ownership, and play an important role in differentiating the seriousrnmanufacturer from the ordinary.rnCircuit breakers are used in a variety of ways. They are mounted in panel boards to protect branch circuit wiring, and they are built into equipment to protect it. For this range of applications a circuit breaker must provide both short circuit and overload protection.
