Reasons for changing from fuses to circuit breakers.
Fuses are a very good method of protecting any electrical line with any voltage. Fuses can be gotten that will trip with just a .001 amp overload. The next best method of electrical overload is a circuit breaker. All circuit breakers are not the same. Some circuit breakers are made to automatically reset after the unit cools in temperature. They reset even if the problem has not been resolved. The auto c/b just keeps resetting until the fire is really burning or the voltage stops. The best protection is a manual resetable circuit breaker. The fault can be repaired and the breaker reset. These are the most expensive, but they rarely become defective.. This type circuit breaker is used in airplanes and other delicate applications. Circuit breakers rarely need replaced as fuse must always be replaced. Some times looking for a special fuse for an A/S at nite is not fun.......
