Phase circuit breakers | Choosing the Right Circuit Breaker
The obvious alternative to a circuit breaker is a fuse, which seemingly offers the advantages of relatively low cost and simplicity. Technical standards will often determine whether you need to use a circuit breaker or a fuse, and although circuit breakers are more expensive and complex, they are advantageous for several reasons. These include:  The condition of a fuse is difficult to estimate and it may degrade over time whereas a circuit breaker can be...
